TIP102

STMicroelectronics · Darlington Transistors · TO-220

TIP102 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 of the NPN Darlington; the datasheet gives IB max 1 A, VEBO max 5 V and a typical 5 kΩ R1 / 150 Ω R2 network.
2 C passive Collector (also the tab); VCEO 100 V, VCBO 100 V, IC 8 A continuous and 15 A peak, with an antiparallel collector-emitter diode.
3 E passive Emitter of the Darlington; the antiparallel diode is connected between emitter and collector, with VF max 2.8 V at IF = 10 A.

CAD (KiCad official)

  • Symbol: TIP102
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: tip102-etched.step / tip102-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tip102.step / tip102.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (4 pp, sha256 4238c6fc76fd220a, retrieved 2026-10-06, tier: lcsc)
  • 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).
