IPL60R125C7AUMA1 Overview
A superjunction (SJ) MOSFET is a high-voltage power MOSFET architecture that uses alternating P/N epitaxial columns in the drift region to overcome the silicon limit of conventional MOSFETs, dramatically reducing RDS(on) per unit area and improving switching loss trade-offs. The CoolMOS C7 family in particular targets hard-switching PFC, TTF (two-transistor forward), and LLC resonant stages in switched-mode power supplies, server PSUs, telecom rectifiers, and industrial welding/induction heating. The superjunction approach (pioneered and named by Infineon) yields substantially lower Eoss turn-off losses than prior generation CoolMOS CP devices while keeping the same 600 V-950 V voltage class.
Key specifications include a 600 V VDS maximum, 17 A ID continuous (Tc), 125 mOhm RDS(on) maximum, and 103 W power dissipation. The C7 generation also features an ultra-low figure-of-merit (RDS(on) x Qg) which reduces gate-drive losses and enables higher switching frequencies (typically 65 kHz to 300 kHz in PFC stages). The PG-VSON-4 package measures approximately 8x8 mm with a large exposed drain pad that doubles as the thermal pad, enabling very low thermal resistance and minimal parasitic source inductance for clean switching waveforms.
Typical applications span telecom/server SMPS power factor correction (PFC) boost stages, LLC half-bridge primary switches, two-transistor forward (TTF) converters, solar inverters, and industrial motor drives. Compared to planar MOSFETs, the C7 family typically halves switching losses in the 600 V class, allowing designers to either raise switching frequency (smaller magnetics) or push power density higher within the same thermal envelope. The IPL60R125C7AUMA1 in particular sits in the mid-current tier of the C7 family, making it well-suited to 1-3 kW power stages where its 125 mOhm on-resistance and 17 A rating align well with typical CCM PFC inductor ripple currents.
When designing with this part, pay close attention to gate-drive voltage and layout. CoolMOS C7 is fully enhanced at +10 V VGS (typical Vth around 3.5 V), so a standard gate-drive supply of 10-12 V is appropriate. The PG-VSON-4 source-pin layout minimizes common-source inductance; nevertheless the gate loop should be kept small with a 10 Ohm-47 Ohm gate resistor to dampen ringing. Thermal design must account for the fact that RDS(on) increases with temperature, so worst-case thermal analysis at 100 C junction is recommended.

Typical Applications
IPL60R125C7AUMA1 is suitable for 6 applications: Telecom/Server PFC Boost Stage, LLC Resonant Half-Bridge Primary, Two-Transistor Forward (TTF) Converter, Solar Inverter DC-DC Boost, Industrial Motor Drive Inverter, Welding and Induction Heating.
Telecom/Server PFC Boost Stage
The IPL60R125C7AUMA1 is purpose-built for 1-3 kW power-factor-correction (PFC) boost stages in server and telecom SMPS, where 600 V bus voltage and hard-switching operation at 65-130 kHz demand the lowest possible switching loss. The CoolMOS C7 family reduces Eoss turn-off loss by roughly 50% versus the prior CoolMOS CP generation, directly improving PFC efficiency by 0.3-0.6% in the 1-3 kW range. The 17 A continuous drain current and 125 mOhm RDS(on) are well matched to CCM-mode inductor ripple currents, while the PG-VSON-4 surface-mount package enables compact, high-density PCB layouts. Use it as the active boost switch in interleaved or single-stage bridgeless totem-pole PFC.
Recommended
LLC Resonant Half-Bridge Primary
The IPL60R125C7AUMA1 fits the primary-side switch position in LLC resonant half-bridge converters used in server, telecom, and industrial power supplies. CoolMOS C7's low output charge (Qoss) and low gate charge (Qg) minimize the dead-time body-diode conduction losses that dominate LLC efficiency at light load, while the 600 V VDS rating provides adequate margin for 400 V rectified mains. The 125 mOhm on-resistance keeps conduction loss acceptable at 1-2 kW, and the PG-VSON-4 footprint allows tight placement of the two primary switches to minimize commutation loop inductance. Suitable for 1-2.5 kW LLC stages operating at 100-200 kHz resonant frequency.
Recommended
Two-Transistor Forward (TTF) Converter
The IPL60R125C7AUMA1 is rated for two-transistor forward converter (TTF) primary switches in industrial and telecom isolated DC-DC converters. TTF topology clamps the drain to input voltage (rather than 2x Vin as in single-transistor forward), so the 600 V rating provides comfortable headroom for 400 V rectified mains plus transformer leakage spikes. Each switch sees half the primary current, so the 17 A continuous drain rating easily supports 1-2 kW designs. CoolMOS C7's low Eoss improves light-load efficiency and enables snubber simplification, while the PG-VSON-4 package keeps the primary-side switch area compact for high-density brick converters.
Recommended
Solar Inverter DC-DC Boost
In solar string inverters, the IPL60R125C7AUMA1 can serve as the high-side switch in DC-DC boost or HERIC inverter bridges operating from PV panel voltages up to 600 V. The CoolMOS C7 family delivers low switching loss at 50-100 kHz, which is critical to maximize inverter efficiency across a wide load range. The 17 A continuous drain rating supports 5-10 kW residential string inverters when paralleled with one additional device, and the PG-VSON-4 footprint enables compact PCB designs that fit in NEMA-rated enclosures. RoHS compliance and 150 C junction rating support outdoor long-life operation.
Recommended
Industrial Motor Drive Inverter
The IPL60R125C7AUMA1 suits the high-side or low-side switch position in 3-phase industrial motor drive inverter bridges (up to 480 V AC mains). CoolMOS C7's low on-resistance and low Qg improve inverter efficiency and reduce thermal stress on the heatsink, while 17 A continuous drain rating supports 3-5 HP (2.2-3.7 kW) drives at typical 8 kHz-16 kHz PWM switching. The PG-VSON-4 surface-mount package is well-suited to FR4-based inverter power modules where compact layout and high isolation spacing are priorities. Industrial temperature range to 150 C junction allows operation in enclosed cabinets.
Recommended
Welding and Induction Heating
The IPL60R125C7AUMA1 fits hard-switched or zero-voltage-switching (ZVS) high-frequency stages in induction heating cooktops and small industrial welding inverters operating from rectified 400 V mains. CoolMOS C7's low Eoss reduces turn-off loss in resonant ZVS operation, enabling higher switching frequencies (50-200 kHz) that shrink magnetic components and improve power density. The 17 A continuous drain and 125 mOhm on-resistance support 2-4 kW output power, while the PG-VSON-4 surface-mount package is favored for SMD-based inverter modules. Designers should add adequate snubbing to manage leakage-inductance spikes during turn-off.

Key Differentiators
- Surface-mount PG-VSON-4 footprint enables compact, low-profile designs (vs IPB65R125C7ATMA2 (TO-263 D2PAK))
- CoolMOS C7 superjunction technology minimizes switching loss (vs STB28N60DM2 (MDmesh DM2 planar))
- 125 mOhm RDS(on) is well matched to 1-3 kW power stages (vs STL33N60M2 (lower RDS(on), higher ID))
Design Notes
Estimated: at full 17 A load, conduction loss equals I^2 x RDS(on) = 17^2 x 0.125 = 36 W. With PG-VSON-4 and proper PCB thermal-via layout (junction-to-ambient ~50 C/W), the junction temperature rises about 50 C above 25 C ambient, easily within the 150 C max. Designers should still de-rate to 50-70% of rated current in continuous operation to keep Tj below 100 C for long-term reliability. Use Infineon's application note AN-2015-04 CoolMOS C7 thermal design guidelines.
The PG-VSON-4 package requires thermal vias under the exposed drain pad (typically 9-16 vias of 0.3 mm diameter) connecting to inner copper planes. The gate loop area must be minimized: route the gate drive return path directly from the source pin (Pin 4) back to the gate-driver ground to avoid common-source inductance that slows switching and causes ringing. Keep drain and source copper pours as large as practical to maximize heat spreading. Reference Infineon PG-VSON-4 land-pattern application note.
Use a 10 Ohm-22 Ohm gate resistor in series with the gate pin to dampen parasitic ringing during fast switching transitions. Place a 100 kOhm gate-to-source pull-down resistor to ensure the MOSFET stays off if the gate driver loses supply. Place a 1 nF-10 nF ceramic bypass capacitor close to the gate-driver supply pin (VDD). Keep high-current drain loops (input cap -> drain -> source -> input cap GND) tight to minimize commutation loop inductance and voltage overshoot.
Do not exceed the absolute maximum VDS of 600 V - account for transformer leakage inductance spikes (typically 30-50% above nominal). Use a TVS clamp or RCD snubber across the primary to limit spike voltages. Do not parallel IPL60R125C7AUMA1 devices without gate-source resistor balancing, as threshold-voltage mismatch can cause current imbalance. Avoid body-diode hard commutation in bridge topologies; CoolMOS C7 body diode is optimized for PFC and is NOT suitable for full-bridge ZVS transition without external Schottky anti-parallel diodes.
