TIP137

STMicroelectronics · Darlington Transistors · TO-220

TIP137 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 control terminal of Darlington transistor with maximum base current rating of 0.3 A and maximum emitter-base voltage of 5 V.
2 Collector passive Collector terminal of Darlington transistor with maximum continuous collector current of 8 A (peak 12 A) and maximum collector-emitter voltage of 100 V, connected to metal tab for thermal dissipation.
3 Emitter passive Emitter terminal forming the main current return path with maximum emitter cut-off current of 5 mA when collector current is zero.

CAD (KiCad official)

  • Symbol: TIP137
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: tip137-etched.step / tip137-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tip137.step / tip137.glb are the bare package body.

Provenance
