IPC100N04S5L1R1ATMA1 Overview
A power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled switch used to efficiently switch or amplify power in electronic circuits. The N-channel enhancement mode means the device is normally OFF at VGS=0 and turns ON when a positive gate-source voltage is applied. The OptiMOS-5 family is Infineon's 5th-generation 40 V trench MOSFET platform, sitting within the broader taxonomy: power MOSFET -> discrete semiconductor -> power transistor -> semiconductor device. Logic-level gate drive (VGS(th) ~1-2 V typical) allows direct PWM control from microcontrollers, gate drivers, or 3.3 V/5 V logic without a charge pump.
Key features include best-in-class figure-of-merit (FOM = RDS(on) × Qg), low package resistance and inductance thanks to the SS08 leadless footprint, AEC-Q101 automotive qualification, MSL1 floor-life unlimited up to 260 °C reflow, 175 °C maximum operating temperature, and 100% avalanche-tested ruggedness. The Green Product (RoHS-compliant) construction supports modern lead-free assembly.
The OptiMOS-5 40 V technology delivers best-in-class switching performance and lower conduction losses, which translates directly into higher efficiency, smaller magnetics, and reduced thermal budgets in high-current 12 V/24 V automotive and industrial designs. The low-inductance SS08 package minimizes voltage overshoot during hard switching at high di/dt.
Typical applications include automotive 12 V/24 V ECUs, electric power steering (EPS), transmission control units (TCU), battery management systems (BMS), DC-DC converters, and motor drive half-bridges. Designers select this part when the system demands high current, ultra-low conduction loss, AEC-Q101 reliability, and a small footprint.
A key design consideration is thermal management: at 100 A into a 1.1 mΩ RDS(on), conduction loss alone is 11 W, so an extensive PCB copper pour or external heatsink is mandatory. The 8-pin TDSON exposed pad must be soldered to a sufficiently large thermal land to keep Tj below 175 °C.

Typical Applications
IPC100N04S5L1R1ATMA1 is suitable for 6 applications: Automotive 12V/24V ECU Power Switching, Electric Power Steering (EPS) Motor Drive, Battery Management System (BMS) Disconnect Switch, DC-DC Buck/Boost Converter Switching Stage, Industrial Motor Drive / Robotics, Hot-Swap / Inrush Current Limiting.
Automotive 12V/24V ECU Power Switching
The IPC100N04S5L1R1ATMA1's 40 V VDS rating and 100 A continuous ID make it well-suited for high-current switching inside 12 V and 24 V automotive electronic control units. Its 1.1 mΩ typical RDS(on) minimizes conduction loss in always-on or high-duty-cycle paths, while AEC-Q101 qualification and 175 °C operating temperature ensure reliability under hood. Placed between the battery rail and downstream DC-DC converters or load switches, it dissipates less than 11 W at full 100 A, compared to 30 W+ for less optimized MOSFETs. The SS08 leadless package also reduces parasitic inductance by ~50% versus D2PAK, lowering switching loss and voltage overshoot in PWM applications above 50 kHz.
Recommended
Electric Power Steering (EPS) Motor Drive
EPS systems demand high peak current (up to 100 A) and low conduction loss in the half-bridge switching stage. The IPC100N04S5L1R1ATMA1's 1.1 mΩ RDS(on) at 10 V VGS keeps I²R losses below 11 W at peak current, enabling the half-bridge to operate at 20 kHz PWM without excessive heating. Its AEC-Q101 qualification and 175 °C junction rating are critical for underhood thermal environments, and the SS08 leadless package provides the low-inductance footprint needed to minimize ringing at high di/dt. Compared to D2PAK predecessors, the IPC100N04S5L1R1ATMA1 shrinks board area by ~60% while delivering equivalent thermal performance when properly land-patterned.
Recommended
Battery Management System (BMS) Disconnect Switch
In 12 V/24 V automotive battery management systems, the IPC100N04S5L1R1ATMA1 serves as a low-loss disconnect switch between the battery and the load. Its 1.1 mΩ RDS(on) introduces only 1.1 mV drop per ampere of quiescent current, preserving battery capacity during long parking periods. The 100 A continuous rating handles inrush from capacitive loads, while AEC-Q101 and 100% avalanche testing guarantee robustness against load-dump transients. Compared to electromechanical relays, the solid-state IPC100N04S5L1R1ATMA1 eliminates contact bounce and provides microsecond switching, improving BMS response time and reducing arcing-related EMI.
Recommended
DC-DC Buck/Boost Converter Switching Stage
The IPC100N04S5L1R1ATMA1's 1.1 mΩ RDS(on) and 40 V VDS rating suit it perfectly as the synchronous low-side or high-side FET in 12 V-to-24 V DC-DC converters delivering 30-80 A. The low gate charge (Qg, part of the OptiMOS-5 best-in-class FOM) enables switching frequencies up to 500 kHz with manageable switching loss, allowing smaller magnetics. The SS08 package's low package inductance reduces drain-voltage overshoot in hard-switched buck topologies, often eliminating the need for snubbers. AEC-Q101 qualification extends its use into 48 V mild-hybrid and e-scooter powertrains where reliability is non-negotiable.
Recommended
Industrial Motor Drive / Robotics
For industrial 24 V brushless DC (BLDC) and stepper motor drives in robotics, the IPC100N04S5L1R1ATMA1 provides the high-current switching muscle needed for 3-phase half-bridges. Its 100 A rating supports motor currents well above 50 A continuous, while the 1.1 mΩ RDS(on) keeps conduction loss manageable in space-constrained robotic joints. The 175 °C operating range covers thermally harsh motor housings, and the SS08 leadless package's small footprint enables compact 3-phase inverter designs. Although AEC-Q101 is automotive-grade, the same underlying silicon is widely used in industrial servo and AGV (automated guided vehicle) systems where reliability is paramount.
Recommended
Hot-Swap / Inrush Current Limiting
In 12 V/24 V hot-swap controllers and eFuse circuits, the IPC100N04S5L1R1ATMA1 acts as the main disconnect FET, controlling inrush into large bulk capacitors on plug-in cards or backplanes. Its 100 A continuous rating handles worst-case load transients, while the 1.1 mΩ RDS(on) introduces minimal voltage drop in normal operation. The 40 V VDS rating covers the full 24 V industrial rail plus transient margin, and AEC-Q101/100% avalanche testing ensures the part survives short-circuit events. The logic-level gate drive allows direct control from a hot-swap controller IC without external charge pump circuitry.

Design Notes
At 100 A continuous drain current into a 1.1 mΩ RDS(on), conduction loss alone is I²R = 11 W. The PG-TDSON-8-34 (SS08) package has a junction-to-PCB thermal resistance around 0.5-1.0 C/W when the exposed pad is soldered to a sufficiently large copper pour (>=1 sq inch on top + bottom layers with thermal vias). Without adequate thermal land, the junction will exceed 175 °C at high duty cycles. Always compute ΔT = P × θJA and keep Tj below 150 °C in normal operation for derating margin. Use multi-layer copper pours with 0.3 mm thermal vias on 1 mm pitch for best results.
The SS08 leadless package requires a specific land pattern per Infineon's package drawing. Use NSMD (non-solder-mask-defined) pads for the source pins to allow solder wicking and reliable thermal contact. The exposed pad (EP) must be soldered with sufficient paste (typically 4-6 thermal via openings 0.3 mm diameter). Keep the high-current drain and source traces short and wide (>=2 oz copper preferred) to minimize PCB parasitic resistance, which otherwise adds to the total RDS(on) of the assembled circuit.
Do not assume the VGS(th) logic-level rating means the FET is fully enhanced at 3.3 V. The IPC100N04S5L1R1ATMA1 requires at least 4.5-10 V VGS to achieve datasheet RDS(on) - a 3.3 V microcontroller GPIO will leave the FET in linear region. Drive the gate with 10 V via a dedicated gate driver IC, or use logic-level FETs only if your design runs the gate at 10 V. Also verify that the gate driver's source/sink current is sufficient to charge the FET's input capacitance within your switching time budget.
Minimize the high-side / low-side gate loop area to reduce switching loss and EMI. In half-bridge layouts, place the gate drive IC as close as possible to the FET gate pin, and route the gate trace over an unbroken ground plane to limit ringing. The SS08 package's small size (~5x6 mm) makes this layout straightforward. For high-frequency applications (>200 kHz), consider adding a small RC snubber or ferrite bead on the gate to dampen oscillation.
