A733

Changjing · Bipolar (BJT) · TO-92

A733 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 terminal of the A733 PNP transistor; the device limits are VEBO -5 V and IC -100 mA continuous.
2 COLLECTOR passive Collector terminal of the A733 PNP transistor; the device limits are VCBO -60 V, VCEO -50 V and IC -100 mA continuous, with PC 250 mW.
3 BASE passive Base terminal of the A733 PNP transistor; the datasheet gives no separate base limit beyond the device maximum ratings (VEBO -5 V, IC -100 mA continuous).

CAD (KiCad official)

  • Symbol: A733
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92 (KiCad packages3D, STEP)
  • 3D model files: a733-etched.step / a733-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); a733.step / a733.glb are the bare package body.
