DDTC114EUAQ-7-F

Diodes Incorporated · Digital Transistors · SOT-323

DDTC114EUAQ-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 (base) through built-in R1 = 10k; input voltage pin 1 to pin 2 is rated -10 to +40 V for DDTC114EUA, with Vl(OFF) 0.5 V min and 1.9 V max Vl(ON) at 10 mA.
2 GND (0) power_in Ground (emitter) reference for the input and supply voltages, with R2 connected between IN and GND.
3 OUT output Output (collector) of the NPN pre-biased transistor; supply voltage pin 3 to pin 2 is rated 50 V maximum and output current 50 mA for DDTC114EUA (100 mA IC max).

CAD (KiCad official)

  • Symbol: DDTC114EUAQ-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: ddtc114euaq-7-f-etched.step / ddtc114euaq-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddtc114euaq-7-f.step / ddtc114euaq-7-f.glb are the bare package body.
