BDW93C

STMicroelectronics · Darlington Transistors · TO-220

BDW93C 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 Darlington power transistor, biasing the internal driver stage through R1 (typ. 10 kΩ).
2 C passive Collector terminal, also connected to the metal mounting tab, rated up to VCEO = 80 V (IB=0) and carrying collector current up to IC = 12 A (ICM = 15 A); integrated anti-parallel diode connects collector to emitter.
3 E passive Emitter terminal of the Darlington pair, cathode side of the integrated collector-emitter freewheeling diode.

CAD (KiCad official)

  • Symbol: BDW93C
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: bdw93c-etched.step / bdw93c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bdw93c.step / bdw93c.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 2026-09-24, tier: manufacturer)
