Input capacitance Ciss is 816 pF typical at 100 V drain bias — a moderate figure that, combined with the gate charge, gives a reasonable switching figure-of-merit (Rds(on) × Qg) for this voltage class. The maximum gate threshold voltage is 5 V at 250 µA drain current, so the 10 V drive level provides solid overdrive for minimum on-resistance. It is ROHS3 compliant.","metaTitle":"STF31N65M5 MOSFET N-Ch 650V 22A TO-220FP, MDmesh V","metaDescription":"STF31N65M5 N-channel 650V 22A MOSFET, 148mOhm Rds(on) at 10V, 45nC Qg.
