Product details

620 V N-channel MOSFET in a fully isolated TO-220FP

The STF4N62K3 is an N-channel MOSFET from STMicroelectronics' SuperMESH3™ series, built for high-voltage switching applications. The device comes in a TO-220-3 Full Pack package, which provides full isolation from the heatsink — no insulating pad or washer is needed, simplifying assembly and improving thermal performance in designs where the tab would otherwise be live.

The 25 W power dissipation rating handles conduction losses with a heatsink.

The base product number is STF4N62, so any future variants or package options will share that root.
