DTA124ECA

Changjiang Electronics Tech (CJ) · Digital Transistors · SOT-23

DTA124ECA from Changjiang Electronics Tech (CJ), 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 of the built-in bias-resistor inverter, with the input voltage limited to -40 V to +10 V (VIN) and VI(off) at most -0.5 V when VCC=-5 V and IO=-100 µA.
2 GND power_in Ground pin as labeled in the datasheet pin connection; the datasheet states no separate electrical limits for this pin.
3 OUT output Output pin with output current limited to -30 mA (IO) and an output voltage VO(on) of at most -0.3 V at IO/II = -10 mA/-0.5 mA.

CAD (KiCad official)

  • Symbol: DTA124ECA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: dta124eca-etched.step / dta124eca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta124eca.step / dta124eca.glb are the bare package body.
