0402ESDA-18N

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

0402ESDA-18N from BORN, 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 T1 passive First terminal of the bi-directional ESD suppressor, which can connect to either the protected signal line or ground because the part is not polarized, with a 1.5pF typ capacitance and <1nA leakage at 18V working voltage.
2 T2 passive Second terminal of the bi-directional ESD suppressor, interchangeable with the first terminal, which clamps ESD at 50V (Vc) with a 100V trigger voltage (Vv ±30%).

CAD (KiCad official)

  • Symbol: 0402ESDA-18N
  • 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)

Provenance

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

  • Datasheet: BORN datasheet (3 pp, sha256 06ccfe45c14e8fbe, retrieved 2026-10-08, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+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).
