PM3401B

Shandong Jingdao Microelectronics · MOSFETs · SOT-23

PM3401B from Shandong Jingdao Microelectronics, in a SOT-23. 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 Gate input Gate terminal; the datasheet rates the gate-source voltage at ±12 V (VGS).
2 Drain passive Drain terminal; the device is rated at a drain-source voltage of -30 V (VDS) and a continuous drain current of -4.2 A (ID).
3 Source passive Source terminal; the datasheet gives no source-specific limit, only the device-level ratings (VDS -30 V, operating and storage temperature -55 to +150 °C).

CAD (KiCad official)

  • Symbol: PM3401B
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: pm3401b-etched.step / pm3401b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pm3401b.step / pm3401b.glb are the bare package body.
