The 175°C junction rating and D2PAK surface-mount package target high-current automotive applications — motor drives, DC-DC converters, and power distribution — where the AEC-Q101 qualification is a non-negotiable for production release. ## Package and mounting The 4 mOhm maximum at 110 A and 10 V translates to about 48 W conduction loss at full rated current — well within the 380 W package dissipation ceiling, but the junction will climb fast if the switching frequency pushes the gate charge (230 nC at 10 V) and the switching losses add up. For a 48 V bus motor drive running at 20 kHz, the conduction loss dominates; the 100 V Vdss gives enough headroom for 48 V rails with 60 V transients. The 9830 pF input capacitance at 50 V means the gate driver needs to source a healthy peak current to keep the switching edges clean. ## AEC-Q101 and the 175°C junction — why it matters for the BOM The AEC-Q101 qualification (series Automotive, AEC-Q101, HEXFET) is the primary differentiator from the commercial HEXFET siblings. It means the part has passed the automotive stress tests — HTRB, H3TRB, temperature cycling, and the rest — so it is accepted in production for under-hood and chassis-domain electronics. ## Sourcing and replacement reality The scorch mark on a dead board tells you the FET failed; a pin-compatible swap from the same voltage class usually brings the board back, but verify the gate drive threshold (4 V max at 250 µA) matches your driver.","metaTitle":"AUIRFS4010-7P N-Channel MOSFET, 100 V, 4 mOhm, AEC-Q101","metaDescription":"Infineon AUIRFS4010-7P N-channel HEXFET MOSFET, 100 V, 190 A, 4 mOhm Rds(on).
