PESD1CAN

UMW · ESD And Surge Protection (TVS/ESD) · SOT-23

PESD1CAN from UMW, 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 LINE1 passive CAN bus line 1 protection terminal; bidirectional TVS anode/cathode node, VRWM=24 V, clamping voltage VC=30 V (max) at IPP=3 A (8/20 µs), reverse leakage IR≤0.5 µA at VRWM.
2 LINE2 passive CAN bus line 2 protection terminal; bidirectional TVS anode/cathode node, VRWM=24 V, clamping voltage VC=30 V (max) at IPP=3 A (8/20 µs), reverse leakage IR≤0.5 µA at VRWM.
3 GND power_in Common ground reference terminal; shared cathode/anode node of both internal back-to-back TVS diodes; rated for peak pulse current IPP=3 A (8/20 µs) and ESD per IEC 61000-4-2 ±30 kV.

  • Symbol: PESD1CAN
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: pesd1can-etched.step / pesd1can-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd1can.step / pesd1can.glb are the bare package body.

Provenance

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

  • Datasheet: UMW datasheet (7 pp, sha256 528aaf00b8c78013, retrieved 2026-09-29, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
