STP3NK90ZFP ST Power MOSFET

The STP3NK90ZFP is an N-channel Zener-protected SuperMESH Power MOSFET from STMicroelectronics in TO-220FP fully insulated package, featuring 900V drain-source voltage and 2.5A continuous drain current. For selection, verify on-resistance for conduction losses, built-in back-to-back Zener diodes for ESD protection up to 3000V HBM, 100% avalanche tested, low gate charge for minimized switching losses, excellent dv/dt capability, and operating junction temperature from -55°C to +150°C. Features include integrated Zener diodes eliminating external protection components, very low intrinsic capacitances for fast switching, and fully insulated TO-220FP package for simplified thermal management without insulating washers. Ideal for offline switching power supplies (SMPS) for industrial equipment operating from high-voltage mains, power factor correction (PFC) stages, LED lighting drivers, flyback converters, and any 900V switching application requiring enhanced ESD/gate protection with insulated package.
