• Switching applications

Description

This device is an N-channel 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.
