2SD1782

Changjing · Bipolar (BJT) · SOT-23

2SD1782 from Changjing, 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 BASE passive Base terminal of the 2SD1782 NPN transistor; the datasheet rates emitter-base voltage VEBO at 5 V.
2 EMITTER passive Emitter terminal of the 2SD1782 NPN transistor; the datasheet rates emitter-base voltage VEBO at 5 V.
3 COLLECTOR passive Collector terminal of the 2SD1782 NPN transistor; the datasheet rates collector-base voltage VCBO at 80 V and continuous collector current IC at 500 mA.

CAD (KiCad official)

  • Symbol: 2SD1782
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: 2sd1782-etched.step / 2sd1782-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2sd1782.step / 2sd1782.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Changjing datasheet (3 pp, sha256 f114528e618ee6f5, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
