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.

Provenance

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

  • Datasheet: UMW datasheet (7 pp, sha256 a4726a32463ed406, retrieved 2026-11-04, tier: lcsc)
  • 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).
