The 800 V drain-to-source rating places it in the high-voltage class for offline power supplies, flyback converters, and auxiliary power stages where the primary-side switch sees rectified mains voltage plus reflected output and leakage inductance spikes. ## On-resistance and gate drive — conduction loss vs switching speed At 4 A continuous drain current (25°C case temperature), the I²R loss at rated Rds(on) reaches 28 W, well within the 60 W power dissipation limit at the case, but the junction-to-case thermal path demands a heatsink for sustained full-current operation. Gate charge is 5 nC typical at 10 V — a low figure that allows direct drive from a PWM controller output without a dedicated gate-driver IC in many designs.","metaTitle":"STMicroelectronics STP5N80K5 N-Ch MOSFET, 800V 4A TO-220","metaDescription":"STP5N80K5 N-channel 800V 4A MOSFET in TO-220 package.
