STW12NK90Z N-channel 900V - 0.72 - 11A - TO-247 Zener-protected SuperMESHTM Power MOSFET General features Type VDSS RDS(on) ID pW STW12NK90Z 900V <0.88 11A 230W Extremely high dv/dt capability 100% avalanche tested Gate charge minimized Very low intrinsic capacitances Very good manufacturing repeatibility TO-247 Description The SuperMESHTM series is obtained through an extreme optimization of ST's well established strip-based PowerMESHTM layout. In addition to Internal schematic diagram 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 MDmeshTM products.
