Gate charge is 42 nC at 10 V, a moderate figure that a standard gate-drive IC can switch without excessive drive current. Input capacitance measures 1250 pF at 50 V Vds, giving a reasonable switching speed for hard-switched topologies in the tens-of-kHz range. The TO-220 through-hole package is straightforward to mount and replace in repair or retrofit scenarios. ## Can it handle a 600 V switching supply? Yes — the 620 V Vdss rating gives margin above a 600 V DC bus, and the 8.4 A continuous current covers many flyback and forward-converter primary-side switches. The 42 nC gate charge keeps switching losses manageable at typical SMPS frequencies. The 750 mOhm Rds(on) is on the higher side for modern designs, so check the conduction loss against your thermal budget before committing the layout.","metaTitle":"STP10N62K3 N-Channel MOSFET, 620 V, 8.4 A, TO-220","metaDescription":"STP10N62K3 N-Channel MOSFET from STMicroelectronics SuperMESH3 series. 620 V Vdss, 8.4 A Id, 750 mOhm Rds(on).
