STW18NK80Z

STW18NK80Z N-channel 800V - 0.34Ω - 19A - TO-247 Zener-protected SuperMESH™ Power MOSFET General features Type STW18NK80Z VDSS 800V RDS(on) <0.38Ω ID pW 19A 350W ■ Extremely high dv/dt capability ■ 100% avalanche tested ■ Gate charge minimized ■ Very low intrinsic capacitances ■ Very good manufacturing repeatibility 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.
