About this product

Description

Marked "K31A60W" on the package with Toshiba's logo (the "T" prefix is dropped in the on-body marking), this is Toshiba's TK31A60W, an N-channel MOSFET rated 600V with an on-resistance of 0.088Ω at 10V gate drive, built in the TO-220SIS package on Toshiba's DTMOSIV process. The isolated TO-220SIS outline simplifies mounting to a heatsink without a separate insulating pad. It's the highest-current member of the same 600V DTMOSIV family that includes the TK12A60W and TK16A60W.

Key features include a low typical drain-source on-resistance of RDS(ON) = 0.073Ω, achieved through a super junction structure (DTMOS), easy gate switching control, and enhancement-mode operation with a gate threshold voltage of 2.7 to 3.7V (VDS = 10V, ID = 1.5mA). It's intended primarily for switching voltage regulator applications.
