SM3401SRL

SPS · MOSFETs · SOT-23

SM3401SRL from SPS, 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 of the P-channel MOSFET (pin 1 per ordering pin assignment G S D); drive with VGS = -10V, -4.5V or -2.5V for the stated RDS(on) specs.
2 S passive Source of the P-channel MOSFET (pin 2 per ordering pin assignment G S D).
3 D passive Drain of the P-channel MOSFET (pin 3 per ordering pin assignment G S D); VDSS -30V, ID -4.4A.

CAD (KiCad official)

  • Symbol: SM3401SRL
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sm3401srl-etched.step / sm3401srl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm3401srl.step / sm3401srl.glb are the bare package body.
