BDX53C

STMicroelectronics · Darlington Transistors · TO-220

BDX53C from STMicroelectronics, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 B input Base terminal of NPN Darlington transistor; maximum base current 0.2 A, maximum base-emitter voltage 5 V.
2 C output Collector terminal (metallic TAB connection); rated for maximum continuous collector current 8 A (peak 12 A) at 100 V maximum collector-emitter voltage.
3 E passive Emitter terminal with integrated antiparallel collector-emitter diode.

CAD (KiCad official)

  • Symbol: BDX53C
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: bdx53c-etched.step / bdx53c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bdx53c.step / bdx53c.glb are the bare package body.
