Symmetrical, non-polarized terminal; connects across the line to be protected. Insulation resistance >1 GΩ (at 100V DC) to A2 until spark-over at ~200V DC (±30%). |+| 2 | A2 | passive | Gas discharge tube electrode 2. Symmetrical, non-polarized terminal; typically tied to protective earth or the opposite side of the protected line. Handles 0.5kA nominal 8/20µs impulse discharge current. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BORN |+| Package | 1206 |+| Category | Circuit Protection |+| Pins | 2 |++## Ordering variants++Same part, different packaging or reel option.++- `BSA201N`++## CAD (KiCad official)++- Symbol: `BSA201N`+- Footprint: `Resistor_SMD:R_1206_3216Metric`+- 3D model: 1206 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [BORN datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588893441699168256) (4 pp, sha256 `c8a087f072198038`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
