DDTC114YCAQ-7-F

Diodes Incorporated · Bipolar (BJT) · SOT23

DDTC114YCAQ-7-F from Diodes Incorporated, in a SOT23. 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 (base) of the pre-biased NPN; input voltage rated -6 to +40 V for DDTC114YCA (absolute maximum, referenced to pin 2).
2 GND power_in Common ground (emitter of the NPN) and reference pin for the supply voltage VCC and input voltage VIN ratings.
3 OUT output Output (collector) of the NPN; output current rated 70 mA for DDTC114YCA (IO), with IC(MAX) 100 mA for all types.

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

  • Symbol: DDTC114YCAQ-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 0.975 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: ddtc114ycaq-7-f-etched.step / ddtc114ycaq-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddtc114ycaq-7-f.step / ddtc114ycaq-7-f.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (6 pp, sha256 0cc5dc96040d959d, retrieved 2026-11-12, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-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).
