Through-hole mounting suits point-of-load positions in PSUs, adapters, and lighting ballasts where the board is wave-soldered. ## Gate charge and switching FOM The ratio — a figure of merit for switching loss — keeps the driver current manageable; a 10 V gate driver sourcing 1 A charges the gate in about 42 ns, well within the edge rate of a typical half-bridge controller. ## Thermal budget and SOA Maximum junction temperature is 150°C, with 34 W power dissipation at the case. The TO-220FP's junction-to-case thermal path is higher than a standard TO-220 because of the full-pack moulding — budget the derating from the 25°C Rds(on) when the junction sits at 125°C, where the on-resistance roughly doubles.","metaTitle":"STF33N65M2 STMicro N-Ch 650V 24A TO-220FP MOSFET","metaDescription":"STF33N65M2 MOSFET, N-Channel, 650V Vdss, 24A Id, 140mOhm Rds(on) at 10V.
