20NK50Z Datasheet (STMicroelectronics)

20NK50Z, N-Channel MOSFET

The SuperMESH™ series is obtained through an extreme optimization of ST’s well established stripbased 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.

20NK50Z Features

* OF GATE-TO-SOURCE ZENER DIODES The built-in back-to-back Zener diodes have specifically been designed to enhance not only the device’s ESD capability, but also to make them safely absorb possible voltage transients that may occasionally be applied from gate to source. In this respect the Zener volta
