DTC123JCA

Changjing · Digital Transistors · SOT-23

DTC123JCA from Changjing, 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 IN input Input pin of the built-in bias-resistor inverter; the absolute maximum input voltage VIN is rated from -5 V to +12 V.
2 GND power_in Ground reference pin of the digital transistor.
3 OUT output Output pin of the digital transistor; the maximum output current IO is rated at 100 mA.

CAD (KiCad official)

  • Symbol: DTC123JCA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: dtc123jca-etched.step / dtc123jca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc123jca.step / dtc123jca.glb are the bare package body.
