PDTC143ZU

Nexperia · Digital Transistors · SOT-323

PDTC143ZU from Nexperia, 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 I input Input pin (base) of the resistor-equipped transistor, with input voltage limited to -5 V to 30 V per the limiting values.
2 GND power_in Ground pin, which the datasheet identifies as the emitter, with no separate voltage limit stated for this pin.
3 O output Output pin (collector) of the transistor, rated for an output current of up to 100 mA and a collector-emitter voltage of 50 V with open base.

CAD (KiCad official)

  • Symbol: PDTC143ZU
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: pdtc143zu-etched.step / pdtc143zu-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pdtc143zu.step / pdtc143zu.glb are the bare package body.

Provenance

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

  • Datasheet: Nexperia datasheet (11 pp, sha256 a701c9d0f17392bd, retrieved 2026-10-09, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
