Power MOSFET in I²PAKFP package

Datasheet — production data

Features

■ Fully insulated and low profile package with

increased creepage path from pin to heatsink

plate

■ Extremely high dv/dt capability

■ 100% avalanche tested

■ Gate charge minimized

Applications

■ Switching applications

Description

This device is an N-channel Zener-protected

Power MOSFET developed using

STMicroelectronics' SuperMESH™ technology,

achieved through optimization of ST's well-

established strip-based PowerMESH™ layout. In

addition to a significant reduction in on-

resistance, this device is designed to ensure a

high level of dv/dt capability for the most

demanding applications.
