BCP55-JSM

JSMSEMI · Bipolar (BJT) · SOT-223

BCP55-JSM from JSMSEMI, in a SOT-223. 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 of the NPN transistor; VEBO max rating is 5 V and the emitter-base breakdown is 5 V min at IE=100 µA.
2 COLLECTOR passive Collector of the NPN transistor; VCEO is 60 V min for BCP55 with continuous collector current of 1 A max.
3 EMITTER passive Emitter of the NPN transistor; the datasheet gives total power dissipation of 1.5 W and junction temperature of 150 °C.

CAD (KiCad official)

  • Symbol: BCP55-JSM
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: bcp55-jsm-etched.step / bcp55-jsm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bcp55-jsm.step / bcp55-jsm.glb are the bare package body.
