DTC143ZUA

Changjing · Digital Transistors · SOT-323

DTC143ZUA from Changjing, 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 Base input of the built-in bias-resistor digital transistor, rated for an input voltage of -5 V to +30 V with R1 = 4.7 kΩ nominal (3.29 to 6.11 kΩ).
2 GND power_in Common ground reference (emitter) for the NPN digital transistor; the datasheet gives no separate electrical limit for this pin.
3 OUT output Collector output of the NPN digital transistor, rated for 100 mA maximum output current and a 0.3 V maximum on-state output voltage at IO/II = 5 mA/0.25 mA.

Key specifications

Parameter Value
Manufacturer Changjing
Package SOT-323
Category Transistors/Thyristors
Pins 3

CAD (KiCad official)

  • Symbol: DTC143ZUA
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: dtc143zua-etched.step / dtc143zua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dtc143zua.step / dtc143zua.glb are the bare package body.
