DTA143ECA-TP

MCC(Micro Commercial Components) · Digital Transistors · SOT-23

DTA143ECA-TP from MCC(Micro Commercial Components), 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 built-in R1 (4.7 kΩ typ); input voltage range is -30 V to 10 V, with VI(off) of -0.5 V min and VI(on) of -3.0 V max.
2 GND power_in Ground (+) terminal of the PNP digital transistor, the emitter side; supply voltage VCC is rated -50 V.
3 OUT output Collector output, rated for output current IO of -100 mA with VO(on) of -0.3 V max at IO=-10 mA.

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

  • Symbol: DTA143ECA-TP
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.92 mm, terminals on the pads, 1.0 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: dta143eca-tp-etched.step / dta143eca-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta143eca-tp.step / dta143eca-tp.glb are the bare package body.

Provenance

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

  • Datasheet: MCC(Micro Commercial Components) datasheet (4 pp, sha256 1ff64c793a794cec, retrieved 2026-11-13, tier: lcsc)
  • 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).
