DDTA143EUA-7-F

Diodes Incorporated · Digital Transistors · SOT-323-3

DDTA143EUA-7-F from Diodes Incorporated, in a SOT-323-3. 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 (base) through built-in R1; input voltage VIN is measured from pin 1 to pin 2, with limits that vary by part type (e.g. +5 to -10 V for DDTA113ZUA).
2 GND(+) power_in Ground/emitter (positive reference) pin, the reference for the input voltage (1 to 2) and supply voltage (3 to 2).
3 OUT output Output (collector) pin; supply voltage VCC from pin 3 to pin 2 is rated -50 V and output current IC(max) is -100 mA.

CAD (KiCad official)

  • Symbol: DDTA143EUA-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323-3 (KiCad packages3D, STEP)
  • 3D model files: ddta143eua-7-f-etched.step / ddta143eua-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddta143eua-7-f.step / ddta143eua-7-f.glb are the bare package body.
