PDTC123JE

Shanghai Prisemi Elec · Digital Transistors · SOT-523

PDTC123JE from Shanghai Prisemi Elec, 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 IN input Input of the built-in bias network (R1 = 2.2 kΩ), with VI(off) at most 0.5 V and VI(on) at least 1.1 V, and an absolute input voltage rating of -5 V to +12 V.
2 GND power_in Ground pin of the digital transistor, serving as the reference for the input and output voltage specifications.
3 OUT output Output (collector) of the NPN digital transistor, rated for 100 mA output current, with VO(on) at most 0.3 V at IO/II = 5 mA/0.25 mA and a supply voltage rating VCC of 50 V.

CAD (KiCad official)

  • Symbol: PDTC123JE
  • 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: pdtc123je-etched.step / pdtc123je-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pdtc123je.step / pdtc123je.glb are the bare package body.
