MDD3401

MDD Microdiode Semiconductor · MOSFETs · SOT-23

MDD3401 from MDD Microdiode Semiconductor, 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 of the P-channel MOSFET; the gate-source voltage is limited to ±12 V (absolute maximum).
2 Source passive Source terminal of the MOSFET, the reference for the gate-source voltage, which is rated at ±12 V maximum.
3 Drain passive Drain terminal of the MOSFET; the drain-source voltage is rated at -30 V and the continuous drain current at -4.2 A.

CAD (KiCad official)

  • Symbol: MDD3401
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mdd3401-etched.step / mdd3401-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mdd3401.step / mdd3401.glb are the bare package body.
