STB21NK50Z

N-channel 500 V, 0.23

Ω, 17 A, D2PAK

Zener-protected superMESH™ Power MOSFET

Features

■ Extremely high dv/dt capability

■ 100% avalanche tested

■ Gate charge minimized

■ Very low intrinsic capacitances

■ Very good manufacturing repeatability

Applications

■ Switching applications

– Automotive

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.
