MMBT4401-TP

MCC Micro Commercial Components · Bipolar (BJT) · SOT-23

MMBT4401-TP from MCC Micro Commercial Components, 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 B input Base of the NPN transistor; emitter-base breakdown V(BR)EBO is 6.0 Vdc min (IE=0.1mAdc, IC=0).
2 E passive Emitter of the NPN transistor; collector current is capable of 600mA with 350mW power dissipation.
3 C passive Collector of the NPN transistor; V(BR)CEO is 40 Vdc min and V(BR)CBO is 60 Vdc min.

CAD (KiCad official)

  • Symbol: MMBT4401-TP
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbt4401-tp-etched.step / mmbt4401-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbt4401-tp.step / mmbt4401-tp.glb are the bare package body.
