BDW94C

STMicroelectronics · Darlington Transistors · TO-220

BDW94C 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 Base input Base terminal of integrated Darlington transistor; maximum base current 0.2 A
2 Collector passive Collector terminal with integrated antiparallel diode to emitter; maximum collector current 12 A, maximum collector-emitter voltage 100 V
3 Emitter passive Emitter terminal of PNP Darlington transistor; maximum total dissipation 80 W at case temperature ≤ 25°C

CAD (KiCad official)

  • Symbol: BDW94C
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: bdw94c-etched.step / bdw94c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bdw94c.step / bdw94c.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (6 pp, sha256 ca781adfaa930550, retrieved 2026-10-06, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-4-5-20251001 (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.
