DDTA114WE-7-F

Diodes Incorporated · Digital Transistors · SOT-523

DDTA114WE-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 through the built-in R1 bias resistor; the absolute maximum input voltage (pin 1 to pin 2) for DDTA114WE is +10 V to -30 V.
2 GND power_in Common/ground reference terminal (emitter) to which the input voltage and supply voltage ratings are referenced; supply voltage VCC (pin 2 to pin 3) is rated -50 V maximum.
3 OUT output Output terminal (collector) with a maximum output current of -100 mA for DDTA114WE (IC(MAX) -100 mA).

CAD (KiCad official)

  • Symbol: DDTA114WE-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: ddta114we-7-f-etched.step / ddta114we-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddta114we-7-f.step / ddta114we-7-f.glb are the bare package body.
