DTC114TCA

Changjing · Bipolar (BJT) · SOT-23

DTC114TCA 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 feeding the built-in bias input resistor R1, which is specified at 7 kΩ min, 10 kΩ typ and 13 kΩ max, so no external input resistor is needed.
2 GND power_in Ground pin of the SOT-23 variant; the datasheet gives no separate electrical limit for this pin.
3 OUT output Output pin of the digital transistor; the device ratings are VCEO 50 V max and continuous collector current IC 100 mA max.

CAD (KiCad official)

  • Symbol: DTC114TCA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: dtc114tca-etched.step / dtc114tca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc114tca.step / dtc114tca.glb are the bare package body.
