DTC114YM

Changjing · Digital Transistors · SOT-723

DTC114YM from Changjing, in a SOT-723. 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 Base input of the built-in bias-resistor network (input resistor R1 is 10 kΩ typical, 7 to 13 kΩ), with input voltage rated from -6 V to +40 V.
2 GND power_in Common ground reference for the NPN transistor and its built-in bias resistors.
3 OUT output Collector output pin, rated for an output current of 70 mA, a peak collector current of 100 mA, and a supply voltage VCC of 50 V maximum.

CAD (KiCad official)

  • Symbol: DTC114YM
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: dtc114ym-etched.step / dtc114ym-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc114ym.step / dtc114ym.glb are the bare package body.
