Product details

Key ratings — what drives the selection

The 650 V drain-source rating provides margin in 400 V DC-link or rectified AC supplies. Gate charge is 17 nC at 10 V.

Package and mounting note

The PG-TO220-3-31 is a TO-220 Full Pack variant with a fully isolated plastic tab. The through-hole leads suit wave-soldering or manual insertion. The component engineer should note that the tab's thermal resistance to case (RthJC) is higher than a standard TO-220 due to the plastic layer — expect a derating factor when calculating junction temperature against the 29.7 W power dissipation limit.
