Typical Applications
IAUCN10S7L290TATMA1 is suitable for 6 applications: 48 V Mild-Hybrid DC-DC Converter, Automotive HVAC Blower & Pump Drivers, Electronic Power Steering (EPS) Controller, Battery Management System (BMS) Protection FET, On-Board Charger (OBC) Auxiliary Circuit, Industrial 24 V / 48 V Bus Switch.
48 V Mild-Hybrid DC-DC Converter
The IAUCN10S7L290TATMA1 is well suited to 48 V mild-hybrid DC-DC converters where 100 V VDS derating covers 48 V bus plus inductive overshoot to 70-80 V. Its 28.6 mΩ max RDS(on) at VGS = 10 V keeps conduction loss under 15 W at 25 A, while the OptiMOS™ 7 cell's reduced gate charge cuts switching loss enough to push fSW above 200 kHz. The top-side cooled PG-LHDSO-10-1 package accepts a thermal interface material plus heatsink for sustained 45 W dissipation in sealed under-hood enclosures. Compared with bottom-cooled DFN parts, the top-side cooling more than doubles sustained current capability at 100 °C ambient.
Recommended
Automotive HVAC Blower & Pump Drivers
In HVAC blower and coolant-pump motor drives, the IAUCN10S7L290TATMA1 serves as the low-side or high-side switch in an H-bridge configuration. Its 27 A continuous drain current handles 8-15 A motor inrush without thermal shutdown, and the 100 V VDS rating tolerates the inductive flyback from motor windings when paired with a flyback Schottky clamp. The automotive AEC-Q100 qualification plus PPAP support meets OEM supplier requirements. The PG-LHDSO-10-1 (SSO10T) footprint is shared across the Infineon automotive MOSFET portfolio, enabling PCB layout reuse across 12 V and 48 V motor variants on the same ECU hardware.
Recommended
Electronic Power Steering (EPS) Controller
The IAUCN10S7L290TATMA1 is suitable for EPS controller power stages where 100 V VDS supports the 12 V or 24 V battery rail plus reverse-battery and load-dump transients. Its 28.6 mΩ max RDS(on) at VGS = 10 V maintains high efficiency in 30-50 A peak torque-assist current pulses, and the top-side cooled PG-LHDSO-10-1 package extracts heat to a heatsink for sustained torque cycling. The AEC-Q100 grade and ISO 26262 process documentation support ASIL-rated steering ECUs. The reduced Qg of OptiMOS™ 7 versus OptiMOS™ 5 also lowers gate-drive losses at the high PWM frequencies used for fine torque control.
Recommended
Battery Management System (BMS) Protection FET
In 12 V and 24 V automotive battery management systems, the IAUCN10S7L290TATMA1 can be deployed as a high-side or low-side protection FET in the battery disconnect path. Its 100 V VDS rating supports 48 V battery stacks in mild-hybrid packs, and the 28.6 mΩ max RDS(on) at VGS = 10 V keeps steady-state I²R loss below 5 W at 15 A continuous discharge. The avalanche-rated body diode and -55 °C to +175 °C junction temperature range ensure survival of cold-crank and load-dump events. The automotive qualification and top-side cooled package meet the high-reliability requirements of OEM battery pack designs.
Recommended
On-Board Charger (OBC) Auxiliary Circuit
The IAUCN10S7L290TATMA1 fits on-board charger auxiliary circuits such as 12 V auxiliary outputs, cooling-fan drivers, and PFC bypass relays. The 100 V VDS rating and 27 A continuous drain current support auxiliary power stages up to roughly 1 kW, while the OptiMOS™ 7 low-Qg design reduces gate-drive stress on the auxiliary transformer-isolated driver. The top-side cooled PG-LHDSO-10-1 footprint simplifies heatsink integration in the cramped OBC enclosure, where PCB area is at a premium. AEC-Q100 qualification and PPAP support streamline OEM validation cycles.
Recommended
Industrial 24 V / 48 V Bus Switch
Outside automotive, the IAUCN10S7L290TATMA1 suits industrial 24 V and 48 V bus switching applications such as PLC outputs, solenoid drivers, and solid-state relays. Its 100 V VDS comfortably tolerates 24 V and 48 V rail transients per IEC 61131-2, and the 28.6 mΩ max RDS(on) at VGS = 10 V keeps dissipation low enough for fan-less industrial enclosures. The wide -55 °C to +175 °C junction temperature range supports outdoor cabinet installations, and the top-side cooled PG-LHDSO-10-1 footprint simplifies thermal management on metal-core PCBs.

Key Differentiators
- OptiMOS 7 generation with ~30% lower gate charge than OptiMOS 5 (vs IAUZ40N10S5N130ATMA1)
- Top-side cooled package for direct heatsink attachment (vs BSC014NE2LSIATMA1 (bottom-cooled DFN))
- 100 V VDS rating covers 48 V mild-hybrid bus plus margin (vs IAUC100N04S6N028ATMA1 (40 V))
Design Notes
Estimated: at ID=20 A continuous, TC=80 °C, RDS(on) rises to roughly 1.8× the 25 °C value (~52 mΩ) producing ~21 W of conduction loss. With a top-side cooled PG-LHDSO-10-1 package and a thermal interface material plus heatsink, junction-to-ambient thermal resistance drops below 5 °C/W, keeping TJ under 175 °C. Without the heatsink the part will exceed thermal limits within minutes. Always validate with a thermocouple on the package top surface during prototype bring-up.
The PG-LHDSO-10-1 (SSO10T 5x7) package has a top-side thermal pad that must be soldered (or thermal-interface-material bonded) to a copper heatsink or top-side spreader. Use 2 oz copper on both top and bottom layers with 9-12 thermal vias (0.3 mm drill, 0.5 mm pad) under the package. Minimize the gate-loop inductance by routing the gate-driver output directly over short, wide traces to pins 1 and 10 to prevent ringing at the Miller plateau.
Do not exceed VGS = ±20 V (per Infineon datasheet) - exceeding this destroys the gate oxide. Source pins must be Kelvin-sensed through a low-inductance path back to the gate driver to avoid gate-oscillation. For high-side (high-side switch) operation, ensure the bootstrap capacitor and gate-drive voltage track the source pin swing, and add a TVS clamp from drain to source to clip inductive flyback within the 100 V VDS rating during motor or solenoid turn-off events.
