DDTC144ECA-7-F

Diodes Incorporated · Digital Transistors · SOT-23

DDTC144ECA-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 bias network (R1 = 47 kΩ nominal for DDTC144ECA); input voltage must stay within -10 V to +40 V relative to pin 2.
2 GND power_in Common ground and emitter reference; the supply and input voltage limits are specified relative to this pin.
3 OUT output Collector output of the NPN pre-biased transistor; supply voltage VCC is rated up to 50 V relative to pin 2 and output current up to 30 mA for DDTC144ECA.

CAD (KiCad official)

  • Symbol: DDTC144ECA-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ddtc144eca-7-f-etched.step / ddtc144eca-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ddtc144eca-7-f.step / ddtc144eca-7-f.glb are the bare package body.
