DTC144EM

TECH PUBLIC · Digital Transistors · SOT-723

DTC144EM from TECH PUBLIC, in a SOT-723. 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 BASE input Base (input) of the NPN digital transistor, connected through the built-in series resistor R1 with base-emitter resistor R2.
2 EMITTER power_in Emitter (ground) of the transistor; connects to circuit ground.
3 COLLECTOR output Collector (output) of the transistor; VCEO and VCBO rated 50Vdc and IC max 100mAdc.

CAD (KiCad official)

  • Symbol: DTC144EM
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: dtc144em-etched.step / dtc144em-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc144em.step / dtc144em.glb are the bare package body.
