DTA143EE

TWGMC · Digital Transistors · SOT-523

DTA143EE from TWGMC, in a SOT-523. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN input Input terminal of the digital transistor, which has built-in bias resistors (R1 = 4.7 kΩ typical); the datasheet gives an input voltage rating of -30 V to +10 V.
2 GND power_in Ground reference terminal for the transistor; the datasheet gives no separate voltage or current limit for this pin.
3 OUT output Output terminal of the transistor; the datasheet gives an output current rating of -100 mA maximum (IO).

CAD (KiCad official)

  • Symbol: DTA143EE
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523 (KiCad packages3D, STEP)
  • 3D model files: dta143ee-etched.step / dta143ee-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dta143ee.step / dta143ee.glb are the bare package body.

Provenance

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

  • Datasheet: TWGMC datasheet (7 pp, sha256 0d665b262c9fc8f9, retrieved 2026-10-09, tier: lcsc)
  • 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: KiCad official libraries (CC-BY-SA 4.0).
