DDTA114EE-7-F

Diodes Incorporated · Digital Transistors · SOT-523

DDTA114EE-7-F from Diodes Incorporated, 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 terminal of the pre-biased transistor (base side, through built-in R1 = 10kΩ); input voltage is limited to +10 V to -40 V relative to pin 2 for the DDTA114EE.
2 GND power_in Common ground reference for the input voltage (pin 1) and supply voltage (pin 3) ratings.
3 OUT output Collector output of the pre-biased PNP transistor; supply voltage VCC is rated up to 50 V from pin 3 to pin 2, and output current is limited to -50 mA for the DDTA114EE (IC max -100 mA).

CAD (KiCad official)

  • Symbol: DDTA114EE-7-F
  • 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: ddta114ee-7-f-etched.step / ddta114ee-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddta114ee-7-f.step / ddta114ee-7-f.glb are the bare package body.
