BD239C

STMicroelectronics · Bipolar (BJT) · TO-220

BD239C from STMicroelectronics, in a TO-220. 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 terminal of the NPN transistor; base current IB is limited to 0.6 A and emitter-base voltage VEBO to 5 V.
2 C passive Collector terminal of the NPN transistor; collector current is rated 2 A continuous and 4 A peak, with VCER of 115 V (RBE = 100 Ω) and VCEO of 100 V.
3 E passive Emitter terminal of the NPN transistor, the common reference for VCE and VBE.

CAD (KiCad official)

  • Symbol: BD239C
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: bd239c-etched.step / bd239c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bd239c.step / bd239c.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (9 pp, sha256 27b7b4f2c0c10e5a, retrieved 2026-11-06, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-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).
