Typical Applications
IPB100N04S4H2ATMA1 is suitable for 6 applications: Automotive Electric Power Steering (EPS), 12V/24V Synchronous Rectification in DC-DC Converters, Automotive Water and Fuel Pump Drivers, Battery Management Protection (12V Li-ion), Industrial 24V Solenoid and Relay Drivers, Hot-Swap and OR-ing Controllers in 12V Distribution.
Automotive Electric Power Steering (EPS)
The IPB100N04S4H2ATMA1 is ideal for EPS motor drive H-bridges where 40V VDS handles 12V load-dump transients with margin. Its 2.4 mΩ RDS(on) minimizes conduction loss at the 60-80A continuous currents typical of EPS assist motors, while the 100A rating provides headroom for peak torque demands. The AEC-Q101 qualification and 175C junction rating satisfy under-hood automotive reliability requirements, and the D2PAK package enables compact PCB layouts with copper-area thermal management directly under the motor controller housing.
Recommended
12V/24V Synchronous Rectification in DC-DC Converters
The IPB100N04S4H2ATMA1 excels as the low-side synchronous rectifier in 12V-input buck and buck-boost converters rated 30-100A output. The 2.4 mΩ RDS(on) at VGS=10V delivers >97% efficiency at full load, while OptiMOS-T2's low Qg (~50nC typical) supports switching frequencies above 200 kHz for smaller magnetics. The 40V VDS rating provides ample margin for 24V industrial bus transients, and the D2PAK-2 surface-mount footprint simplifies thermal management via PCB copper pour directly under the drain tab.
Recommended
Automotive Water and Fuel Pump Drivers
The IPB100N04S4H2ATMA1 is well-suited for brushless DC water pump and fuel pump driver stages operating from 12V automotive supply. Its 100A continuous drain current supports peak motor start-up surges, while the AEC-Q101 qualification and 100% avalanche testing ensure reliability under the inductive kickback events typical of BLDC commutation. The D2PAK package withstands the 125C ambient temperatures of engine-bay mounting, and the 2.4 mΩ RDS(on) reduces controller heat dissipation to enable fully sealed IP67 pump housings.
Recommended
Battery Management Protection (12V Li-ion)
The IPB100N04S4H2ATMA1 serves as a robust low-side disconnect switch in 12V Li-ion battery management systems requiring 80-100A continuous discharge ratings. Its ultra-low 2.4 mΩ RDS(on) adds minimal voltage drop in series with the battery, preserving usable capacity, while the 40V VDS handles the 16.8V max charge voltage with substantial margin. The MSL1 rating and 260C peak reflow compatibility support high-volume automotive BMS manufacturing, and the OptiMOS-T2 avalanche ruggedness protects against reverse-battery fault events.
Recommended
Industrial 24V Solenoid and Relay Drivers
The IPB100N04S4H2ATMA1 is well-matched to industrial 24V solenoid and high-current relay driver outputs in PLC and process control systems. Its 40V VDS rating covers 24V nominal plus IEC 61131-2 transient events with margin, and the 2.4 mΩ RDS(on) minimizes dissipation at the 50-100A peak solenoid currents typical of hydraulic and pneumatic actuators. The D2PAK package's surface-mount form factor enables high-density DIN-rail module designs, while the 175C junction rating supports operation in sealed industrial enclosures.
Recommended
Hot-Swap and OR-ing Controllers in 12V Distribution
The IPB100N04S4H2ATMA1 functions as the series pass element in 12V hot-swap and redundant power OR-ing controllers for server and telecom distribution. Its 2.4 mΩ RDS(on) keeps voltage drop below 250mV at 100A, preserving regulation margin for downstream DC-DC converters, while OptiMOS-T2's fast body-diode reverse recovery supports high-frequency OR-ing switching without shoot-through. The 40V rating tolerates inductive kickback from cable harnesses, and the D2PAK package provides the thermal mass for sustained 100A operation in 1U rack-mount equipment.

Design Notes
Estimated: At full 100A load with VIN=12V and VOUT (drain tab copper) dissipation, conduction loss is approximately P = I² × RDS(on) = 100² × 0.0024 = 24W. With a D2PAK theta_JA of ~40C/W on 1 sq inch of 2oz copper, junction temperature rise above ambient is roughly 40 × 24 = 960C (exceeding 175C max). For continuous 100A operation, at least 6 sq inches of 2oz copper spread directly under the drain tab is required, plus a thermal interface to a heatsink for sustained high-current loads. For typical 50-60A automotive loads, the 24W dissipation drops to 7.2W and standard PCB thermal design suffices.
The D2PAK drain tab is electrically hot and thermally conductive. Maximize copper area on the drain tab PCB land pattern - at least 1 sq inch minimum, with 4-6 sq inches preferred for high-current applications. Use multiple thermal vias (0.3mm drill, 1mm pitch) directly under the tab to inner copper planes. Keep the gate trace short (<20mm) and route the source return (Kelvin connection) separately back to the gate driver ground to avoid dynamic RDS(on) degradation from source-inductance-induced gate ringing.
Do not operate the IPB100N04S4H2ATMA1 below VGS=4.5V; partial enhancement yields RDS(on) 3-5x higher than spec, causing thermal runaway. Add a gate-source Zener (15V) close to the gate pin to protect against VGS transients from drain dv/dt coupling. For half-bridge circuits, always insert dead-time (typically 200-500ns) between high-side and low-side gate signals to prevent shoot-through. Verify avalanche energy (EAS) during unclamped inductive switching events stays below the datasheet rating to avoid cumulative device degradation.
MSL1 rating allows unlimited floor-life exposure, but the part should still be baked (125C for 24h) if stored >2 years before reflow. Use a reflow profile with peak temperature 245-260C for 20-30s above 217C (JEDEC J-STD-020). Lead-free SAC305 solder paste is standard. The D2PAK land pattern should follow IPC-7351 nominal density (SMD-IPC-7351-TO-263) with 2.5mm wide drain tab pad to maximize thermal contact area.
