PESD0402AS05

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

PESD0402AS05 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 One terminal of the bidirectional single-line ESD protection; continuous operating voltage is 5.0 V max, leakage is 100 nA max at 5 V DC, and it is rated for IEC 61000-4-2 ESD of 8 kV contact and 15 kV air.
2 2 passive Other terminal of the bidirectional single-line ESD protection; continuous operating voltage is 5.0 V max, leakage is 100 nA max at 5 V DC, and it is rated for IEC 61000-4-2 ESD of 8 kV contact and 15 kV air.

CAD (KiCad official)

  • Symbol: PESD0402AS05
  • 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: pesd0402as05-etched.step / pesd0402as05-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd0402as05.step / pesd0402as05.glb are the bare package body.

Provenance

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

  • Datasheet: YFW datasheet (5 pp, sha256 7ca2366db45375ef, retrieved 2026-10-18, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-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).
