The gate drive voltage is specified at 10 V for the rated Rds(on); a lower gate voltage will increase the on-resistance. Input capacitance Ciss is 310 pF at 25 V drain-source, consistent with the modest die size. ## Thermal and environmental ratings Maximum power dissipation is 45 W at the case temperature. Gate-source voltage is clamped at ±30 V maximum — a common zener-protected input that tolerates transient spikes on the gate drive line. ## Package: DPAK (TO-252) surface-mount The DPAK footprint is a standard power-package layout; the reeled format is Tape & Reel. ## Lifecycle and sourcing — NRND status For a BOM line already using this device, sourcing is available against an RFQ through the surplus and broker channel. Buyers evaluating new designs should select an active N-channel MOSFET with equivalent 500 V / 3 A ratings and a DPAK footprint.","metaTitle":"STD4NK50ZT4 N-Channel MOSFET, 500V 3A, SuperMESH, NRND","metaDescription":"STMicroelectronics STD4NK50ZT4 N-Channel MOSFET, 500V Vdss, 3A Id, 2.7 Ohm Rds(on), SuperMESH series, DPAK package.
