The 800 V rating gives 50% derating margin on a typical 400 V DC bus (PFC output or rectified 230 VAC), which is the conventional practice for reliable off-line power supplies. The 16 A continuous rating is package-limited at 25°C case; at a 100°C case temperature the current must be derated per the SOA curve in the datasheet, and the 190 W power dissipation ceiling (Tc) sets the heatsink requirement. ## Conduction and switching numbers that drive the thermal budget Input capacitance Ciss is 1000 pF typical at 100 V drain-source bias, which influences the turn-on delay and the driver's peak current requirement. The maximum gate-source voltage is ±30 V. ROHS3 compliant, no exemptions. For a production line that needs a clean 800 V N-channel with a standard D²PAK footprint and active lifecycle, this is a straightforward BOM fit.","metaTitle":"STB23N80K5 MOSFET N-CH 800V 16A D2PAK, MDmesh K5","metaDescription":"STB23N80K5 N-channel 800 V 16 A MOSFET in D²PAK, MDmesh K5 series.
