PESD3V3L1UA

UMW · ESD And Surge Protection (TVS/ESD) · SOD-323

PESD3V3L1UA from UMW, in a SOD-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 Pin1 passive The datasheet's SOD-323 pinning section labels this terminal as Pin1 of the unidirectional TVS but does not state whether it is the anode or the cathode.
2 Pin2 passive The datasheet's SOD-323 pinning section labels this terminal as Pin2 of the unidirectional TVS but does not state whether it is the anode or the cathode.

CAD (KiCad official)

  • Symbol: PESD3V3L1UA
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: pesd3v3l1ua-etched.step / pesd3v3l1ua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd3v3l1ua.step / pesd3v3l1ua.glb are the bare package body.
