Total gate charge is 28 nC at 10 V, with a ±30 V maximum gate-source rating that leaves headroom for gate-drive overshoot on a 12 V or 15 V rail. Input capacitance Ciss is 535 pF at 25 V drain-source, which together with the gate charge sets the drive current needed for the target switching frequency — a 28 nC gate at 100 kHz draws 2.8 mA average from the driver, well within a standard MOSFET driver's capability. The TO-220 through-hole package (TO-220-3) allows direct heatsink mounting with a screw or clip — the 70 W maximum power dissipation assumes an infinite heatsink at 25°C case temperature.","metaTitle":"STP5NK50Z N-Channel MOSFET, 500 V, 4.4 A, TO-220","metaDescription":"STMicroelectronics STP5NK50Z SuperMESH™ N-channel MOSFET, 500 Vdss, 4.4 A continuous drain, 1.5 Ohm Rds(on) at 10 V.
