Its defining spec is a maximum on-resistance of 2.8 mOhm at 76 A drain current with 10 V gate drive. ## Gate charge and drive — what 209 nC means for the driver Total gate charge at 10 V is 209 nC. The input capacitance is 8250 pF at 25 V drain-source. ## 175 °C junction — thermal headroom for power-dense builds The operating junction temperature range is -55 °C to 175 °C. It is ROHS3 compliant. ## Through-hole TO-220 — field-swappable, no hot-air needed The TO-220-3 / TO-220AB package is a through-hole part with a metal tab for screw-mounting to a heatsink. That means it can be replaced on site with a soldering iron and a screwdriver — no reflow oven, no hot-air station. For field-service repairs, this part goes into the kit without hesitation.","metaTitle":"IRF3703PBF HEXFET N-Ch MOSFET, 30V 210A TO-220AB, 2.8 mOhm","metaDescription":"IRF3703PBF N-channel HEXFET MOSFET, 30V Vdss, 210A continuous drain, 2.8 mOhm Rds(on) max at 10V.
