DTC144ECA

TECH PUBLIC · Digital Transistors · SOT-23

DTC144ECA from TECH PUBLIC, 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 (BASE) input Base input through built-in R1 of 47kΩ (min 32.9kΩ, max 61.1kΩ) with R2 of 47kΩ to emitter; input voltage range -10 to +40 V.
2 GND (EMITTER) power_in Emitter, used as the ground reference of the digital transistor.
3 OUT (COLLECTOR) output Collector output of the NPN digital transistor, rated 30 mA output current and 100 mA maximum collector current, supply voltage -50 V.

CAD (KiCad official)

  • Symbol: DTC144ECA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: dtc144eca-etched.step / dtc144eca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc144eca.step / dtc144eca.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
