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.
