DTC123EE

Changjing · Digital Transistors · SOT-523

DTC123EE from Changjing, in a SOT-523. 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 of the built-in bias-resistor inverter stage, with input voltage VIN rated from -10 V to +12 V in the maximum ratings.
2 GND power_in Ground pin, listed as GND in the SOT-523 pin connections; the datasheet gives no separate electrical limit for this pin.
3 OUT output Output pin with output current IO rated at 100 mA maximum, and supply voltage VCC rated up to 50 V in the maximum ratings.

CAD (KiCad official)

  • Symbol: DTC123EE
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 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: dtc123ee-etched.step / dtc123ee-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc123ee.step / dtc123ee.glb are the bare package body.
