STP4NK60Z N-channel MOSFET, 600 V drain-source, 4 A continuous drain, SuperMESH series.
Gate-source voltage rating is ±30 V; threshold is 4.5 V at 50 µA drain current.
TO-220-3 through-hole package, 70 W power dissipation at Tc=25 °C. Operating junction temperature is 150 °C.
The base product number is STP4NK60; the Z suffix denotes the SuperMESH generation. If you are cross-shopping within the 600 V, 4 A class, the TO-220 footprint is standard, but confirm the gate charge and Rds(on) against your switching frequency and thermal budget.
