BC857BHZGT116

ROHM Semicon · Bipolar Transistors - BJT · SOT-23

BC857BHZGT116 from ROHM Semicon, in a SOT-23. 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 Emitter passive Emitter of the PNP transistor; VEBO is limited to -5 V and emitter-base breakdown BVEBO is -5 V min at IE = -50μA.
2 Base passive Base of the PNP transistor; VCE(sat) is specified at IB = -0.5mA and -5mA.
3 Collector passive Collector of the PNP transistor; VCEO is -45 V and continuous collector current IC is -100 mA maximum.

CAD (KiCad official)

  • Symbol: BC857BHZGT116
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc857bhzgt116-etched.step / bc857bhzgt116-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc857bhzgt116.step / bc857bhzgt116.glb are the bare package body.
