Zener-protected SuperMESH™ Power MOSFET
Features
■Extremely high dv/dt capability
■100% avalanche tested
■Gate charge minimized
Application
■Switching applications
Description
The SuperMESH™ series is obtained through an
optimization of STMicroelectronics’ well-
established strip-based PowerMESH™ layout. In
addition to pushing on-resistance significantly
lower, it also ensures very good dv/dt capability
for the most demanding applications. This series
complement STs’ full range of high voltage power
MOSFETs.

Doc ID 9479 Rev 7 5/17
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 voltage is
appropriate to achieve an efficient and cost-effective intervention to protect the device’s
integrity. These integrated Zener diodes thus avoid the usage of external components.
