BTC900N from BORN, in a 1812. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A1 passive Gas discharge tube electrode 1. Symmetric bidirectional overvoltage-protection terminal; connects between the protected line (e.g. Tip/Ring) and ground or the opposite electrode. Fires at DC spark-over ~90 V (±30%) and clamps at ~15 V arc voltage while diverting surge current (up to 2.0 kA, 8/20 μs).
2 A2 passive Gas discharge tube electrode 2. Symmetric counterpart to electrode 1; the two electrodes are electrically equivalent and the tube is non-polarized. Under normal operation the electrodes are open (>=1 GΩ insulation @50 V DC); above the spark-over voltage the tube ionizes and shunts surge current between the two terminals.
