DDTA114ECA-7-F

Diodes Incorporated · Digital Transistors · SOT-23

DDTA114ECA-7-F from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

Pinout

Pin Name Type Function
1 IN input Base input through the 10kΩ R1 series resistor; the rated input voltage (pin 1 to pin 2) for DDTA114ECA is +10 to -40 V.
2 GND (+) power_in Common ground/positive reference (emitter) of the PNP pre-biased transistor, against which VIN and VCC are rated.
3 OUT output Collector output; supply voltage VCC (pin 3 to pin 2) is rated -50 V and output current IO is rated -50 mA for DDTA114ECA.

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

CAD (land: KiCad; 3D: generated from the datasheet)

  • Symbol: DDTA114ECA-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.025 mm tall, datasheet A, nominal). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: ddta114eca-7-f-etched.step / ddta114eca-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddta114eca-7-f.step / ddta114eca-7-f.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Diodes Incorporated datasheet (5 pp, sha256 238b94f121ac7005, retrieved 2026-11-13, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: land: KiCad official libraries (CC-BY-SA 4.0); 3D: generated from the datasheet's package dimensions (provenance.model_3d_generated).
