The through-hole I2PAK package handles the 234 W power dissipation budget required in engine bay and chassis-domain environments. This part carries an Automotive grade designation and is AEC-Q101 qualified, which means it meets the stress test and reliability requirements for automotive applications including under-hood and transmission-attached modules. The qualification documentation supports PPAP submission for Tier-1 and OEM programs. ## 3.1 mOhm Rds(on) — the switching loss trade-off The maximum on-resistance of 3.1 mOhm at 10 V gate drive is among the lowest for a 40 V through-hole MOSFET in this package class. The 79 nC typical gate charge at 10 V means the driver must deliver a 79 nC pulse per switching cycle; pair this with a gate driver rated for at least 2 A peak to keep transition times under 50 ns at 100 A. The 6200 pF input capacitance at 25 V drain-source adds to the drive demand — budget gate-drive power accordingly. ## Package and mounting The I2PAK (TO-262) through-hole package suits designs where a heatsink is mounted directly to the device tab, common in automotive power modules. The through-hole leads handle the 100 A continuous drain current when the tab is properly heat-sunk to the PCB or chassis.","metaTitle":"BUK7E3R1-40E,127 Nexperia N-Channel MOSFET","metaDescription":"Nexperia BUK7E3R1-40E,127 N-Channel TrenchMOS MOSFET, 40V, 100A, 3.1mΩ Rds(on) at 10V.
