2N3906-TA

Changjing · Bipolar (BJT) · TO-92

2N3906-TA 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 PNP transistor; the datasheet gives no electrical limit for this pin alone, and the emitter-base breakdown voltage is listed as -5 V (min) with IC=0.
2 BASE input Base terminal of the PNP transistor, which drives the device; base-emitter saturation voltage is -0.95 V max at IC=-50 mA, IB=-5 mA.
3 COLLECTOR passive Collector terminal of the PNP transistor; collector-base breakdown voltage is -40 V min at IC=-10 uA and collector-emitter breakdown voltage is -40 V min at IC=-1 mA.

CAD (KiCad official)

  • Symbol: 2N3906-TA
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92 (KiCad packages3D, STEP)
  • 3D model files: 2n3906-ta-etched.step / 2n3906-ta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2n3906-ta.step / 2n3906-ta.glb are the bare package body.
