N-channel 500 V, 0.23

Ω, 17 A SuperMESH™ Power MOSFET

Zener-protected TO-220, TO-247, TO-220FP, D2PAK

Features

■ Extremely high dv/dt capability

■ 100% avalanche tested

■ Gate charge minimized

■ Very low intrinsic capacitances

■ Very good manufacturing repeatability

Application

■ Switching applications

Description

The SuperMESH™ series is obtained through an

extreme optimization of ST’s well established

strip-based 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.

Such series complements ST full range of high

voltage MOSFETs including revolutionary

MDmesh™ products.
