Gate charge is 44 nC at 10 V, and input capacitance measures 1280 pF at 50 V Vds, giving a figure of merit (Qg × Rds(on)) around 11.9 nC·Ω that is competitive for its voltage class. The TO-220-3 through-hole package (supplier device package TO-220) allows straightforward heatsink attachment with a single screw. Maximum power dissipation is 125 W at case temperature, and the junction temperature rating is 150°C. This MOSFET is sized for the 100–500 W range of off-line power converters, PFC pre-regulators, and DC-DC stages where 650 V blocking margin is needed for 240 VAC rectified rails (≈380 VDC) plus switching overshoot. The 270 mΩ Rds(on) keeps conduction losses manageable at 7–10 A RMS. It is not suited for low-voltage (<100 V) synchronous rectification or battery-management circuits where a 30–100 V device with lower Rds(on) would be more efficient.","metaTitle":"STP20NM65N N-Channel MOSFET, 650 V, 15 A, TO-220, Obsolete","metaDescription":"STP20NM65N MDmesh™ II N-Channel MOSFET, 650 V drain-source, 15 A continuous, 270 mΩ Rds(on).

For existing designs, the part can be sourced through independent distribution against an RFQ.
