STF12NK65Z ST Power MOSFET

The STF12NK65Z is an N-channel Zener-protected SuperMESH Power MOSFET from STMicroelectronics in TO-220FP fully insulated package, featuring 650V drain-source voltage, 0.57Ω max on-resistance, and 10A continuous drain current . For selection, verify built-in back-to-back Zener diodes for ESD protection, 100% avalanche tested for ruggedness, low gate charge for minimized switching losses, excellent dv/dt capability for demanding applications, and operating junction temperature from -55°C to +150°C. Features include SuperMESH technology optimized from PowerMESH layout for significantly reduced on-resistance, integrated Zener protection eliminating external components, and fully insulated package for simplified thermal management. Ideal for offline switching power supplies (SMPS), power factor correction stages, high-voltage DC-DC converters, LED lighting drivers, and any 650V switching application requiring enhanced ESD/gate protection with insulated package.
