STB21NK50Z - N-channel MOSFET

General Description

The SuperMESH™ series is obtained through an extreme optimization of ST’s well established strip-based PowerMESH™ layout.

In addition to pushing on-resistance significantly down, special care is taken to ensure a very good dv/dt capability for the most demanding applications.
