Typical Applications
IPD35N10S3L26ATMA2 is suitable for 6 applications: 48V Automotive DC-DC Converter, Automotive E-Fuse and Load Switch, Electric Power Steering (EPS) Driver, Industrial Synchronous Rectification (100 V bus), Solenoid and Relay Driver Modules, Brushed DC Motor H-Bridge.
48V Automotive DC-DC Converter
The IPD35N10S3L26ATMA2 is engineered for 48 V mild-hybrid automotive DC-DC converters stepping 48 V down to 12 V for auxiliary loads. Its 100 V V<sub>DS</sub> rating provides 50 V headroom above the 48 V rail, comfortably absorbing inductive transients and load-dump events. With 24 mOhm maximum R<sub>DS(on)</sub> at VGS = 10 V, conduction loss at typical 15-20 A loads stays well under 10 W per switch, and the 71 W power-dissipation rating at Tc with DPAK tab cooling keeps the junction within the AEC-Q101 thermal envelope. The AEC-Q101 screening further qualifies it for OEM 48 V power-module programs.
Recommended
Automotive E-Fuse and Load Switch
Solid-state e-fuses in 48 V automotive power distribution replace traditional pyrotechnic fuses with a controllable MOSFET-based switch. The IPD35N10S3L26ATMA2 suits this role because its 100 V V<sub>DS</sub> handles 48 V bus transients, the 35 A continuous Id covers most branch-circuit loads, and the 24 mOhm R<sub>DS(on)</sub> keeps steady-state voltage drop below 1 V at full load. The DPAK exposed tab also dissipates fault-current heating during the milliseconds of short-circuit interruption before the gate driver commands turn-off. AEC-Q101 qualification is mandatory for OEM e-fuse modules.
Recommended
Electric Power Steering (EPS) Driver
Electric power steering requires a robust, AEC-Q101-qualified MOSFET capable of PWM-switching motor currents up to 30 A continuously at 12 V or 48 V rails. The IPD35N10S3L26ATMA2's 35 A continuous drain current at Tc, low 24 mOhm R<sub>DS(on)</sub>, and DPAK package make it a strong candidate for the H-bridge switches in EPS controllers. Its OptiMOS-T trench technology also reduces switching loss at the typical 20 kHz PWM frequency of EPS drives, lowering inverter heating and improving steering-effort smoothness under transient load.
Recommended
Industrial Synchronous Rectification (100 V bus)
In industrial 60-100 V bus synchronous-rectifier stages (solar optimizers, battery formation, telecom 48 V), the IPD35N10S3L26ATMA2 functions as the low-side MOSFET replacing Schottky diodes. Its 100 V rating handles bus transients, the 24 mOhm R<sub>DS(on)</sub> reduces conduction loss versus a diode, and the 71 W DPAK thermal envelope supports sustained rectification at 20-30 A. The trench OptiMOS-T technology further delivers low Qg, reducing drive losses at 100-300 kHz switching frequencies typical of modern isolated DC-DC stages.
Recommended
Solenoid and Relay Driver Modules
Automotive and industrial solenoid/relay driver modules require a MOSFET that can absorb the inductive kickback of a de-energized coil. The IPD35N10S3L26ATMA2's 100 V V<sub>DS</sub> rating, combined with its avalanche-rated single-pulse drain current, makes it suitable for direct switching of 12 V or 24 V solenoids without an external TVS clamp. The 35 A continuous Id handles inrush current of even large contactors, and the DPAK footprint is a drop-in match across solenoid-driver PCB variants used by Tier-1 automotive module suppliers.
Recommended
Brushed DC Motor H-Bridge
Brushed DC motor H-bridges for throttle, valve, and seat-position actuators use four N-channel MOSFETs of which two are high-side and two low-side. The IPD35N10S3L26ATMA2 fits both positions in 12 V and 24 V brushed-motor systems up to 35 A. Its low 24 mOhm R<sub>DS(on)</sub> reduces I²R loss and keeps the H-bridge thermal budget within the DPAK footprint's dissipation limit, while its AEC-Q101 qualification makes it acceptable for under-hood and chassis-mounted motor modules. The exposed tab also simplifies PCB heatsink integration.

Design Notes
Estimated: at VIN = 48 V, VOUT = 12 V, ID = 20 A continuous conduction in a synchronous buck low-side switch, the IPD35N10S3L26ATMA2 dissipates approximately I²R × (1-D) = 20² × 0.024 × 0.25 = 2.4 W. The PG-TO252-3-11 DPAK package on a 1-square-inch copper pour on a 1 oz FR-4 board typically achieves ThetaJA around 50 C/W, yielding roughly 120 C junction at 100 C ambient - within the AEC-Q101 thermal envelope but requiring verification against your specific PCB stack-up and airflow. Add thermal vias under the tab to inner copper planes for additional reduction.
Keep the gate-drive loop area as small as possible to minimize parasitic inductance that causes VGS ringing and possible shoot-through. Place the gate-driver IC within 10 mm of the gate pin, route gate and source return on adjacent layers, and use a local 10-100 ohm gate resistor plus an optional TVS or 5.1 V Zener from gate to source to clamp below the +/- 20 V VGS maximum. The exposed tab is internally connected to the drain, so PCB copper under the tab doubles as both thermal relief and drain node.
Do not exceed VGS = +/- 20 V absolute maximum; many gate drivers produce 12-15 V which is acceptable, but a misconfigured bootstrap with a 24 V supply will destroy the gate oxide. Also note that AEC-Q101 does not guarantee operation beyond the datasheet's electrical limits - derate continuous Id to roughly 50-60% of the 35 A Tc-rating at realistic PCB case temperatures near 100 C. Finally, confirm EAS (single-pulse avalanche energy) rating from the datasheet before using this part in an unclamped inductive-switching topology.
