# BTC201N

**BORN** · Gas Discharge Tube Arresters (GDT) · 1812

BTC201N 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 | A | passive | GDT electrode (anode/cathode, symmetric); DC spark-over voltage 200 V ±20%, maximum impulse spark-over 750 V at 1 kV/µs, nominal impulse discharge current 2.0 kA (8/20 µs), insulation resistance ≥1 GΩ at 100 V DC, capacitance ≤0.8 pF at 1 MHz. |
| 2 | B | passive | GDT electrode (anode/cathode, symmetric); electrically identical to pin 1 - device is bidirectional and non-polarised; arc voltage ~15 V at 1 A. |

## CAD (KiCad official)

- Symbol: `BTC201N`
- Footprint: `Resistor_SMD:R_1812_4532Metric`
- 3D model: 1812 (KiCad packages3D, STEP)
- 3D model files: `btc201n-etched.step` / `btc201n-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `btc201n.step` / `btc201n.glb` are the bare package body.
