# 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. |

## CAD (KiCad official)

- 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.
