DDTC143XCA-7-F

Diodes Incorporated · Digital Transistors · SOT-23

DDTC143XCA-7-F from Diodes Incorporated, in a SOT-23. 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 Base input of the built-in R1 (4.7kΩ) bias network; for DDTC143XCA the input voltage (pin 1 to pin 2) is rated -7 V to +20 V.
2 GND power_in Ground reference (emitter) for the device; the supply VCC is referenced from pin 3 to pin 2 with an absolute maximum of 50 V.
3 OUT output Collector output of the NPN pre-biased transistor; output current is limited to 100 mA maximum (IC(MAX)) for this device.

CAD (KiCad official)

  • Symbol: DDTC143XCA-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ddtc143xca-7-f-etched.step / ddtc143xca-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddtc143xca-7-f.step / ddtc143xca-7-f.glb are the bare package body.
