STD5NK50ZT4 ST Power MOSFET

The STD5NK50ZT4 is an N-channel Zener-protected SuperMESH Power MOSFET from STMicroelectronics in DPAK surface-mount package, featuring 500V drain-source voltage and 4.4A continuous drain current (5A pulsed). For selection, verify built-in back-to-back Zener diodes for ESD protection up to 3000V HBM, 100% avalanche tested for ruggedness, low gate charge for minimized switching losses, excellent dv/dt capability, and operating junction temperature from -55°C to +150°C. Features include SuperMESH technology for best-in-class on-resistance, integrated Zener protection eliminating external components, and very low intrinsic capacitances for fast switching. Ideal for offline switching power supplies (SMPS) as auxiliary power or low-power primary switch, LED lighting drivers, power factor correction (PFC) stages in low-power applications, high-voltage DC-DC converters, and any 500V switching application requiring enhanced ESD/gate protection in DPAK surface-mount package.
