Description
Product status link
STB5NK50Z-1
These high-voltage devices are Zener-protected N-channel Power MOSFETs
developed using the SuperMESH™ technology by STMicroelectronics, an
optimization of the well-established PowerMESH™. In addition to a significant
reduction in on-resistance, these devices are designed to ensure a high level of dv/dt
capability for the most demanding applications.

The built-in back-to-back Zener diodes are specifically designed to enhance the ESD performance of the device.
The Zener voltage facilitates efficient and cost-effective device integrity protection, thus eliminating the need for
additional external componentry.
