Product details

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

That is the number to use for conduction-loss calculations at the nominal operating point. Input capacitance is 680 pF at 50 V drain-source — a light capacitive load on the driver, so switching edges stay clean without excessive ringing.

The TO-220FP package has a single mounting hole for a screw or clip.

Frequently asked questions

What is the Rds(on) of STF5N62K3?

This is the value to use for worst-case conduction-loss budgeting.
