STP12NK30Z

STMicroelectronics · MOSFETs · TO-220-3

STP12NK30Z from STMicroelectronics, in a TO-220-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate; VGS rated ±30 V max, with built-in back-to-back Zener diodes to the source for ESD protection (3000 V HBM) and threshold of 3 to 4.5 V at ID = 50 µA.
2 D passive Drain; VDS rated 300 V max, continuous current 9 A at TC = 25°C (36 A pulsed), also connected to the mounting tab.
3 S passive Source; main current return terminal of the MOSFET, with a body diode to the drain rated 9 A continuous (ISD).

CAD (KiCad official)

  • Symbol: STP12NK30Z
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220-3 (KiCad packages3D, STEP)
  • 3D model files: stp12nk30z-etched.step / stp12nk30z-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stp12nk30z.step / stp12nk30z.glb are the bare package body.
