Input capacitance Ciss is 10250 pF at 25 V drain bias — the driver must charge this capacitance through the gate loop inductance, so a low-inductance layout with the driver placed within 10 mm of the gate pin is recommended. ## 175 °C junction — thermal headroom for harsh environments The 175 °C upper limit is rated for a 40 V FET. Power dissipation is 294 W at case temperature. ## Package and procurement — PG-TO263-7-900 on Tape & Reel The AUIRFS8408-7TRL ships in the PG-TO263-7-900 package — a 7-lead D2PAK variant with an exposed drain tab. ROHS3 compliance is confirmed on the lifecycle record. ## Date-code traceability and authenticity check For a high-current part like this, the laser etch on the PG-TO263-7-900 body should show a consistent date-code font matching Infineon's plant marking for that week. The exposed drain tab should have a uniform solderable finish — any re-sanding or re-marking on the tab face is a red flag. Tape & Reel lots from independent distribution must show continuous date-code ranges; a single reel with mixed codes from different months warrants decap X-ray to verify the die matches the HEXFET® cell structure.","metaTitle":"AUIRFS8408-7TRL HEXFET N-Ch 40V 240A D2PAK, 1mOhm Rds(on)","metaDescription":"Infineon AUIRFS8408-7TRL N-channel MOSFET, 40V Vdss, 240A Id, 1mOhm Rds(on) max at 10Vgs.
