MPSA14

Changjing · Bipolar (BJT) · TO-92

MPSA14 from Changjing, in a TO-92. 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 EMITTER passive Emitter of the NPN Darlington transistor; VEBO max 10 V and collector current up to 0.5 A continuous.
2 BASE passive Base of the NPN Darlington transistor; VBE max 2.0 V at VCE=5V, IC=100mA.
3 COLLECTOR passive Collector of the NPN Darlington transistor; VCEO max 30 V, VCBO max 30 V, IC continuous 0.5 A.

CAD (KiCad official)

  • Symbol: MPSA14
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92 (KiCad packages3D, STEP)
  • 3D model files: mpsa14-etched.step / mpsa14-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mpsa14.step / mpsa14.glb are the bare package body.
