STB21NK50Z

STB21NK50Z N-channel 500 V, 0.23 Ω, 17 A, D2PAK Zener-protected superMESH™ Power MOSFET Features Type STB21NK50Z ■ ■ ■ ■ ■ VDSS 500 V RDS(on) max < 0.27 Ω ID 17 A Pw 190 W Extremely high dv/dt capability 100% avalanche tested Gate charge minimized Very low intrinsic capacitances Very good manufacturing repeatability 3 1 D²PAK Applications ■ Switching applications – Automotive Figure 1. Internal schematic diagram 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. Table 1.
