2SA1941-O

TOSHIBA · Bipolar (BJT) · TO-3P-3

2SA1941-O from TOSHIBA, in a TO-3P-3. 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; absolute maximum base current is -1 A and emitter-base voltage is -5 V.
2 C passive Collector terminal, connected to the heat sink tab; absolute maximum VCEO and VCBO are -140 V and collector current is -10 A.
3 E passive Emitter terminal, the common reference for the PNP power transistor.

CAD (KiCad official)

  • Symbol: 2SA1941-O
  • Footprint: Package_TO_SOT_THT:TO-3P-3_Vertical
  • 3D model: TO-3P-3 (KiCad packages3D, STEP)
  • 3D model files: 2sa1941-o-etched.step / 2sa1941-o-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2sa1941-o.step / 2sa1941-o.glb are the bare package body.

Provenance

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

  • Datasheet: TOSHIBA datasheet (4 pp, sha256 76dc253c96745f39, retrieved 2026-11-06, 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).
