Input capacitance of 866 pF at 100 V Vds confirms the switching node capacitance is manageable for a standard gate-driver IC. For a BOM planner, this removes the risk of a sudden obsolescence-driven redesign during the product's expected production run. ## Package and thermal handling — TO-220-3 The TO-220-3 through-hole package is a standard vertical-mount power package. Maximum power dissipation is 170 W at case temperature, which assumes a proper heatsink with thermal interface material. For a rework or repair scenario, the through-hole leads are straightforward to solder and desolder with a standard iron or hot-air station.","metaTitle":"STP17N80K5 N-Channel MOSFET, 800 V, 14 A, TO-220-3","metaDescription":"STP17N80K5 N-Channel MOSFET from STMicroelectronics MDmesh K5 series. 800 V Vdss, 14 A Id, 340 mOhm Rds(on) at 10 V.
