TPESD0402G18V

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · 0402

TPESD0402G18V from TECH PUBLIC, 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 Terminal 1 of the bidirectional single-line ESD suppressor, connected to the protected signal line or to GND since the device is not polarized; rated ±15 kV air and ±8 kV contact per IEC 61000-4-2.
2 2 passive Terminal 2 of the bidirectional single-line ESD suppressor, connected to the protected signal line or to GND since the device is not polarized; rated ±15 kV air and ±8 kV contact per IEC 61000-4-2.

CAD (KiCad official)

  • Symbol: TPESD0402G18V
  • 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: tpesd0402g18v-etched.step / tpesd0402g18v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpesd0402g18v.step / tpesd0402g18v.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (6 pp, sha256 a1889c5ab457d0cb, 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).
