DDA143TU-7-F

Diodes Incorporated · Digital Transistors · SOT-363

DDA143TU-7-F from Diodes Incorporated, in a SOT-363. 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 E1 passive Emitter of PNP transistor 1, the reference for the input (1)-(2) and the supply (1)-(6) ratings (VCC -50V max, VIN +5V max for DDA143TU).
2 B1 input Base (input) of transistor 1 through the 4.7kΩ R1 resistor, with input voltage rated +5V max referenced to pin 1.
3 C2 passive Collector (output) of transistor 2, rated IO -100mA with VCC -50V max between (4) and (3).
4 E2 passive Emitter of PNP transistor 2, the reference for the input (4)-(5) and the supply (4)-(3) ratings (VCC -50V max).
5 B2 input Base (input) of transistor 2 through the 4.7kΩ R1 resistor, with input voltage rated +5V max referenced to pin 4.
6 C1 passive Collector (output) of transistor 1, rated IO -100mA with VCC -50V max between (1) and (6).

CAD (KiCad official)

  • Symbol: DDA143TU-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363 (KiCad packages3D, STEP)
  • 3D model files: dda143tu-7-f-etched.step / dda143tu-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dda143tu-7-f.step / dda143tu-7-f.glb are the bare package body.
