PDTB123YT

Nexperia · Digital Transistors · SOT-23

PDTB123YT 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 resistor-equipped PNP transistor, with bias resistor R1 = 2.2 kΩ (±10 %); the input voltage is limited to +5 V positive and -20 V negative.
2 GND power_in Ground (emitter) connection of the transistor; the datasheet specifies it as the emitter terminal and gives no separate voltage limit for this pin.
3 O output Output (collector) of the transistor, rated for a maximum output current of -500 mA with VCEO of -50 V.

  • Symbol: PDTB123YT
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: pdtb123yt-etched.step / pdtb123yt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pdtb123yt.step / pdtb123yt.glb are the bare package body.
