PDTA143ZT

Nexperia · Digital Transistors · SOT-23

PDTA143ZT from Nexperia, 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 I input Input (base) of the built-in PNP transistor, connected through the internal 4.7 kΩ bias resistor R1; the datasheet limits the input voltage to -30 V to 5 V.
2 GND power_in Ground pin, which is the emitter of the built-in transistor and the reference for the internal bias network R1 and R2.
3 O output Output (collector) of the built-in transistor, rated for an output current of -100 mA and a collector-emitter voltage of -50 V.

CAD (KiCad official)

  • Symbol: PDTA143ZT
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: pdta143zt-etched.step / pdta143zt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pdta143zt.step / pdta143zt.glb are the bare package body.

Provenance

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

  • Datasheet: Nexperia datasheet (10 pp, sha256 7bfa466bab668d31, retrieved 2026-10-13, 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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
