YFW · ESD And Surge Protection (TVS/ESD) · 0402

PESD0402B18 from YFW, in a 0402. 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 1 passive Bi-directional ESD protection terminal 1 of the single-line TVS diode (symmetric, no polarity); connect to the protected signal line or to ground, with continuous operating voltage up to 18.0 V.
2 2 passive Bi-directional ESD protection terminal 2 of the single-line TVS diode (symmetric, no polarity); connect to the protected signal line or to ground, with continuous operating voltage up to 18.0 V.

CAD (KiCad official)

  • Symbol: PESD0402B18
  • Footprint: Diode_SMD:D_0402_1005Metric
  • 3D model: 0402, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.4 mm nominal 0402 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: pesd0402b18-etched.step / pesd0402b18-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd0402b18.step / pesd0402b18.glb are the bare package body.

Provenance

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

  • Datasheet: YFW datasheet (5 pp, sha256 ee9e5749f75cda0f, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-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).
