IPD90N03S4L02ATMA1 Overview
A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled majority-carrier switch that uses a gate oxide to modulate a conductive channel between source and drain. In the OptiMOS-T2 family, an N-channel trench-gate cell shrinks the R_DS(on) x area figure of merit, falling under the broader power MOSFET hierarchy: trench MOSFET -> power MOSFET -> discrete semiconductor. This places the part firmly inside Infineon's automotive-grade discrete semiconductor portfolio optimized for 12 V/24 V vehicle bus systems.
Key features include a 2.2 mΩ maximum R_DS(on) at VGS=10 V, 4.5 V to 10 V gate-drive compatibility for direct MCU/PWM control, and an operating junction range up to 175°C. The device is AEC-Q101 qualified, MSL1 rated for up to 260°C peak reflow, and shipped in a Green Package that is RoHS compliant. Per datasheet, the part is 100% avalanche tested, providing proven ruggedness for unclamped inductive switching events common in motor windings and solenoid loads.
The OptiMOS-T2 cell architecture uses a vertical trench with a split-gate structure that reduces gate charge (Qg) and Miller capacitance (Cgd) versus the prior OptiMOS generation. This lowers switching energy at high PWM frequencies (50-300 kHz), enabling smaller magnetics in synchronous buck converters and reduced dead-time loss in half-bridges. The 175°C junction rating also sustains continuous high-current operation in sealed under-hood enclosures.
Typical applications include automotive electronic power steering (EPS), brushed DC and BLDC motor drives, LED driving and headlamp load management, DC-DC synchronous buck and synchronous rectification stages, battery protection and hot-swap circuits, and industrial solenoid/relay drivers. The wide safety margin between 90 A continuous rating and typical 30-40 A application currents supports robust inrush handling.
When designing with this part, derate continuous drain current to roughly 60-70 A in a real PCB layout with limited copper pour, and verify gate-drive strength to fully enhance the channel (VGS ≥ 10 V recommended). The exposed tab on the PG-TO252-3-11 package must be soldered to a thermal pad of at least 1 sq. in. copper for full 136 W dissipation capability.

Typical Applications
IPD90N03S4L02ATMA1 is suitable for 6 applications: Automotive Electronic Power Steering (EPS), BLDC and Brushed DC Motor Drive, Automotive LED Headlamp and Load Driver, Synchronous Buck DC-DC Converter Low-Side Switch, Battery Protection and Hot-Swap Circuit, Industrial Solenoid and Relay Driver.
Automotive Electronic Power Steering (EPS)
The IPD90N03S4L02ATMA1 is well-suited to EPS motor drive half-bridges because its 30 V VDS safely covers 12 V automotive bus transients up to ~24 V load-dump, while the 2.2 mΩ R_DS(on) at VGS=10 V minimizes conduction loss across the 50-80 A peak motor currents seen during parking maneuvers. The AEC-Q101 qualification is mandatory for under-hood EPS ECUs, and the 100% avalanche rating provides headroom for the regenerative braking current spikes that occur when current is commutated through the body diode during PWM dead-time. The DPAK's 136 W dissipation rating, when paired with a 1 sq. in. copper pour, sustains continuous torque assist without thermal throttling. Designers typically run the part at 25 kHz PWM with VGS=10 V for fully-enhanced switching; the 4.5 V VGS rating also enables direct 5 V MCU logic drive in low-power modes.
Recommended
BLDC and Brushed DC Motor Drive
For 12 V / 24 V BLDC motor inverters and brushed DC H-bridges, the IPD90N03S4L02ATMA1's 90 A continuous rating delivers a 2-3x safety margin above typical 30-40 A motor currents, ensuring long-term reliability under locked-rotor inrush. Its 2.2 mΩ R_DS(on) at VGS=10 V keeps I²R conduction loss below 5 W at 50 A, simplifying thermal design in compact motor-control PCBs. The OptiMOS-T2 cell's low gate charge (Qg) and Miller capacitance enable 50-100 kHz PWM frequencies with reduced switching loss, which is critical for sensorless BLDC trapezoidal commutation. The 175°C junction rating also permits operation in sealed motor housings where ambient can reach 85-100°C.
Recommended
Automotive LED Headlamp and Load Driver
High-brightness LED headlamps and DRL/turn load drivers benefit from the IPD90N03S4L02ATMA1's low R_DS(on) which, at typical 5-10 A LED currents, dissipates only 0.1-0.4 W — eliminating the need for bulky heatsinks in tight headlamp housings. The 30 V VDS rating covers 12 V bus with comfortable transient headroom, and the part's 4.5 V VGS turn-on enables direct drive from 5 V logic for daytime running light PWM dimming at 200-1000 Hz. AEC-Q101 qualification, MSL1 reflow rating, and Green Package RoHS compliance meet automotive lighting module requirements. The 100% avalanche test rating provides a safety margin for the inductive transients generated by the LED wiring harness inductance during PWM edge transitions.
Recommended
Synchronous Buck DC-DC Converter Low-Side Switch
As the low-side synchronous rectifier in a 12 V-to-3.3 V/5 V/1.8 V buck converter, the IPD90N03S4L02ATMA1's 2.2 mΩ R_DS(on) at VGS=10 V produces 1-2% efficiency gain versus Schottky diode rectification at loads above 10 A. The low gate charge of the OptiMOS-T2 cell enables 300-500 kHz switching with minimal dead-time loss, allowing smaller inductors in compact point-of-load designs. The 30 V rating provides adequate margin above 12 V nominal bus voltage plus transients. The exposed-drain DPAK tab solders directly to a copper thermal pad that doubles as a heatsink, supporting 20-30 W continuous output without airflow.
Recommended
Battery Protection and Hot-Swap Circuit
In 12 V lead-acid or Li-ion battery management systems, the IPD90N03S4L02ATMA1 serves as the reverse-battery and over-current disconnect switch. Its 2.2 mΩ R_DS(on) keeps the discharge path loss under 50 mV at 25 A, well within e-fuse accuracy budgets. The 100% avalanche rating and 175°C junction limit provide robust fault handling during external short-circuit events where the MOSFET must absorb the inductive kick from upstream wiring before the fuse clears. AEC-Q101 qualification supports automotive BMS deployment. Designers typically parallel two parts for 100 A+ applications, taking advantage of the DPAK's tab-pinned drain for symmetric current sharing.
Recommended
Industrial Solenoid and Relay Driver
For driving 12 V/24 V solenoids, relays, and contactors in industrial automation, the IPD90N03S4L02ATMA1's 90 A ID handles inrush currents well above the steady-state holding current, while the 30 V VDS tolerates flyback voltage when the coil is de-energized (with a freewheeling diode clamp). The OptiMOS-T2 cell's fast switching enables PWM proportional solenoid control for hydraulic valves, and the AEC-Q101/extended temperature rating permits deployment in sealed factory enclosures up to 85°C ambient. The part's 100% avalanche test means it survives unclamped turn-off transients on the inductive load without an external TVS clamp, simplifying the BOM.

Key Differentiators

- Proven OptiMOS-T2 cell with established AEC-Q101 supply chain (vs IPD090N03LGATMA1)
- Lower R_DS(on) per area than 60 V parts in the same package (vs BSC014N06NSATMA1)
Design Notes
Estimated: at 50 A continuous conduction with VGS=10 V and 2.2 mΩ R_DS(on), conduction loss is roughly 5.5 W. With a 1 square inch copper pour on a 2 oz FR-4 PCB the thermal resistance RθJA is approximately 50°C/W, yielding a 28°C temperature rise above 25°C ambient — well within the 175°C junction limit. For 90 A full-load operation increase copper area to at least 4 square inches or add forced airflow to keep junction rise below 100°C. Always solder the exposed drain tab; a floating tab voids the thermal path and causes rapid thermal runaway at high current.
Place a 1 µF / 100 V ceramic bypass capacitor (X7R or X7S dielectric) between gate and source as close as possible to the gate pin to suppress Miller-induced turn-on during high dv/dt switching events. Use a gate-drive resistor of 10-47 Ω to limit ringing and control rise time; values below 5 Ω risk gate-oxide ringing exceeding the ±20 V VGS absolute maximum. Keep the gate-trace short and away from the drain tab to minimize parasitic coupling — the exposed tab carries switching node voltage and can capacitively couple into a long gate trace.
Do not operate the IPD90N03S4L02ATMA1 at VGS below 4.5 V for continuous high-current loads — partial enhancement dramatically increases R_DS(on) and pushes the part into thermal runaway. For 12 V bus systems prefer VGS=10 V drive from a dedicated gate-driver IC rather than direct MCU GPIO. The exposed drain tab is electrically live; do not rely on PCB solder mask for tab-to-heatsink isolation. Always include a TVS clamp (e.g. SMBJ33CA) across the drain-source of inductive loads, even though the part is 100% avalanche tested — repeated avalanche events degrade R_DS(on) over time.
