BTC801N

BORN · Gas Discharge Tube Arresters (GDT) · 1812

BTC801N from BORN, in a 1812. 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 Terminal 1 passive One end-cap terminal of the gas discharge tube, non-polarized and interchangeable with the other terminal; 800V±30% DC spark-over voltage (BTC801N), 1.0KA 8/20μs nominal impulse discharge current, 4KV 10/700μs impulse withstand.
2 Terminal 2 passive The other end-cap terminal of the gas discharge tube, non-polarized and interchangeable with the other terminal; maximum impulse spark-over 1600V at 1KV/μs, capacitance 1pF max at 1MHz, insulation resistance 1GΩ min at 100V DC.

  • Symbol: BTC801N
  • Footprint: Resistor_SMD:R_1812_4532Metric
  • 3D model: 1812 (KiCad packages3D, STEP)
  • 3D model files: btc801n-etched.step / btc801n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); btc801n.step / btc801n.glb are the bare package body.

Provenance

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

  • Datasheet: BORN datasheet (4 pp, sha256 2d7d15d8fda51ced, 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).
