DTC143ZE-MS

MSKSEMI · Digital Transistors · SOT-523

DTC143ZE-MS from MSKSEMI, in a SOT-523. 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 internal R1 = 4.7 kΩ (3.3 to 6.1 kΩ) with R2 = 47 kΩ to the emitter.
2 EMITTER power_in Emitter (ground) of the transistor; the internal R2 resistor returns to this pin.
3 COLLECTOR output Collector (output) of the transistor, rated for VCEO 50 V, VCBO 50 V and IC 100 mA maximum.

CAD (KiCad official)

  • Symbol: DTC143ZE-MS
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 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: dtc143ze-ms-etched.step / dtc143ze-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc143ze-ms.step / dtc143ze-ms.glb are the bare package body.
