DDTA123YUA-7-F

Diodes Incorporated · Digital Transistors · SOT-323

DDTA123YUA-7-F from Diodes Incorporated, in a SOT-323. 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 terminal to the built-in bias network (R1); the DDTA123YUA input voltage is rated from +5 V to -12 V.
2 GND power_in Common ground reference (labeled GND(+) on the schematic) for the supply and input voltages; the supply voltage VCC from pin 3 to pin 2 is rated at -50 V.
3 OUT output Output terminal (PNP collector); the DDTA123YUA output current is rated at -100 mA.

Materials and finish

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: DDTA123YUA-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323, generated on the KiCad land (body 1.25 x 2.1 mm, terminals on the pads, 0.95 mm tall, datasheet A, midpoint of min and max). 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: ddta123yua-7-f-etched.step / ddta123yua-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddta123yua-7-f.step / ddta123yua-7-f.glb are the bare package body.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (4 pp, sha256 d7af473cdacc488b, retrieved 2026-11-13, 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).
