JSMSEMI · Bipolar (BJT) · TO-3PN

2SA1492 from JSMSEMI, in a TO-3PN. 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 terminal of the PNP transistor; emitter-base voltage is limited to -6 V and continuous base current to -4 A.
2 COLLECTOR passive Collector terminal; collector-base and collector-emitter voltage are rated at -180 V and continuous collector current at -15 A.
3 EMITTER passive Emitter terminal of the PNP transistor, reference for the -6 V emitter-base voltage limit.

CAD (KiCad official)

  • Symbol: 2SA1492
  • Footprint: Package_TO_SOT_THT:TO-3P-3_Vertical
  • 3D model: TO-3PN (KiCad packages3D, STEP)
  • 3D model files: 2sa1492-etched.step / 2sa1492-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2sa1492.step / 2sa1492.glb are the bare package body.
