Gate charge is 60 nC at 10 V, a moderate figure that a standard gate-drive IC can handle without excessive switching loss. Input capacitance is 1800 pF at 50 V drain-source, giving a rough idea of the drive current needed for a target rise time. ## TO-220FP full-pack — isolated tab, no heatsink pad The TO-220-3 Full Pack (TO-220FP) package has a fully molded, isolated backside — no exposed metal tab. The 30 W dissipation ceiling at case temperature reflects that. Mounting torque and screw length matter: the plastic body can crack if over-torqued. STMicroelectronics lists the STF21NM60ND as obsolete. For a sustainment program or repair depot, the replacement search should start with ST's current FDmesh™ and MDmesh™ series parts in the same voltage and current class — 600 V, 17 A, TO-220FP — but every candidate must be checked for pin-compatibility, gate charge, and on-resistance.","metaTitle":"STF21NM60ND N-Channel MOSFET, 600V 17A, TO-220FP, Obsolete","metaDescription":"STF21NM60ND N-Channel MOSFET, 600V drain-source, 17A continuous, 220mOhm Rds(on), TO-220FP full-pack.
