40 V N-channel from the OptiMOS™ 6 family
The Infineon IAUA250N04S6N005AUMA1 is an N-channel power MOSFET built on the OptiMOS™ 6 trench technology. It is rated for a drain-source voltage of 40 V and delivers a maximum continuous drain current of 62 A at 25 °C case temperature. The key on-resistance figure is 0.55 mOhm at 100 A with a 10 V gate drive, which keeps conduction losses low in high-current paths like battery management, motor drives, and DC-DC converters. The device is housed in a PG-HSOF-5-5 surface-mount package with an exposed pad for thermal transfer to the PCB.
Temperature range and deployment environment
The operating junction temperature range of -55 °C to 175 °C qualifies this MOSFET for under-hood automotive, industrial motor drives, and outdoor telecom power supplies where ambient heat and load cycling are severe. The 175 °C maximum is a genuine design margin for fault conditions or sustained high-current operation, but the thermal resistance from junction to case must be managed with a good PCB thermal pad and vias to keep the die temperature within the safe operating area.
Lifecycle and supply posture
The IAUA250N04S6N005AUMA1 is listed as Active in production with ROHS3 compliance. There is no end-of-life notice or last-time-buy window on record.
