DDTC114ECA-7-F

Diodes Incorporated · Digital Transistors · SOT-23

DDTC114ECA-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 Input through the built-in 10kΩ base resistor R1 (DDTC114ECA), with input voltage VIN rated -10 to +40V relative to pin 2.
2 GND power_in Ground (0V) reference for the input and the output supply voltage.
3 OUT output Output (collector) of the NPN transistor, with supply voltage VCC rated 50V relative to pin 2 and output current IO of 50mA for DDTC114ECA.

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

  • Symbol: DDTC114ECA-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: ddtc114eca-7-f-etched.step / ddtc114eca-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddtc114eca-7-f.step / ddtc114eca-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 b71e1c1af45adb44, 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).
