AD-DTC123YCA

Changjing · Digital Transistors · SOT-23

AD-DTC123YCA 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 of the built-in inverter, connected through R1 (1.54 to 2.86 kΩ) to the base, with VI(off) min 0.3 V, VI(on) max 3 V and an absolute input voltage range of -5 to 12 V.
2 GND power_in Ground connection, tied to the emitter of the NPN transistor and to R2.
3 OUT output Open-collector output of the NPN transistor, rated for up to 100 mA output current and 50 V supply voltage.

CAD (KiCad official)

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