DDTC124EUA-7-F

Diodes Incorporated · Digital Transistors · SOT-323

DDTC124EUA-7-F from Diodes Incorporated, in a SOT-323. 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 pin, connected through the built-in input resistor R1 (22k nominal) to the transistor base; the absolute maximum input voltage from pin 1 to pin 2 is -10 V to +40 V for DDTC124EUA.
2 GND power_in Ground reference pin; the absolute maximum supply voltage VCC is specified from pin 3 to pin 2 at 50 V, and the input voltage is specified from pin 1 to pin 2.
3 OUT output Output pin (collector of the internal NPN transistor) with a supply voltage limit of 50 V from pin 3 to pin 2 and an output current limit of 30 mA for DDTC124EUA.

CAD (KiCad official)

  • Symbol: DDTC124EUA-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: ddtc124eua-7-f-etched.step / ddtc124eua-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddtc124eua-7-f.step / ddtc124eua-7-f.glb are the bare package body.
