BD242B

STMicroelectronics · Bipolar (BJT) · TO-220

BD242B 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 PNP power transistor; base current IB is rated up to 1 A (absolute maximum).
2 C passive Collector terminal; collector current IC rated 3 A continuous (5 A peak), with collector-emitter voltage VCEO up to 80 V for the B-suffix device.
3 E passive Emitter terminal; emitter-base voltage VEBO rated up to 5 V (IC = 0).

CAD (KiCad official)

  • Symbol: BD242B
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: bd242b-etched.step / bd242b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bd242b.step / bd242b.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (4 pp, sha256 543298da312a9c51, retrieved 2026-09-24, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.2, primary claude-sonnet-5 (text+vision), consensus claude-opus-4-8 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
