The 55 nC total gate charge at 10 V is moderate for a 600 V, 34 A FET; a standard gate-driver IC can push through that charge in a few tens of nanoseconds, keeping switching losses manageable in hard-switched topologies up to the 100 kHz range. Input capacitance Ciss is 2370 pF at 100 V drain-source. Gate charge Qg is 55 nC at 10 V.","metaTitle":"STF42N60M2-EP MOSFET, N-Ch 600V 34A TO-220FP, 87mOhm","metaDescription":"STF42N60M2-EP N-channel 600V 34A MOSFET in TO-220FP. 87mOhm Rds(on) at 17A, 55nC gate charge.

The base part STF42N60M2 shares the same 600 V / 34 A rating and TO-220FP package, but the -EP version is the recommended choice for new designs where lower Rds(on) or tighter parametric control is required.
