DTA114YM

Changjing · Digital Transistors · SOT-723

DTA114YM 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 pin of the built-in bias network; the datasheet's absolute input voltage limit is -40 V to +6 V, with input resistor R1 specified at 10 kΩ (7 to 13 kΩ).
2 GND power_in Ground reference pin shared by the input and output of the inverter circuit.
3 OUT output Collector output pin; output current is limited to -70 mA and peak collector current to -100 mA, with VO(on) at most -0.3 V at IO/II = -5 mA/-0.25 mA.

CAD (KiCad official)

  • Symbol: DTA114YM
  • 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: dta114ym-etched.step / dta114ym-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta114ym.step / dta114ym.glb are the bare package body.
