DTC123YCA

Changjing · Digital Transistors · SOT-23

DTC123YCA from Changjing, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN input Inverter base input with integrated bias resistors; Vi(off)=0.3V, Vi(on)=3V, accepts -5V to +12V
2 GND power_in Emitter and ground reference
3 OUT output Collector output signal, active low; VO(on)=0.1-0.3V at IO=10mA, IO(max)=100mA

CAD (KiCad official)

  • Symbol: DTC123YCA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: dtc123yca-etched.step / dtc123yca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc123yca.step / dtc123yca.glb are the bare package body.
