BLM3401S3

TECH PUBLIC · MOSFETs · SOT-23

BLM3401S3 from TECH PUBLIC, 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 G input Gate; gate-source voltage limit is ±12 V, with threshold VGS(th) of -0.7 V min to -1.3 V max at ID=-250µA.
2 S passive Source of the P-channel MOSFET; drain-source voltage rated -30 V and continuous drain current -4.2 A.
3 D passive Drain of the P-channel MOSFET; VDS = -30 V, continuous ID = -4.2 A, pulsed IDM = -30 A.

CAD (KiCad official)

  • Symbol: BLM3401S3
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: blm3401s3-etched.step / blm3401s3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); blm3401s3.step / blm3401s3.glb are the bare package body.
