# BTC102N

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

BTC102N 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 | T1 | passive | Gas discharge tube terminal 1. Symmetrical, non-polarized electrode of the two-terminal SMD gas arrester; connect to the protected line or to ground. In the off state presents >1GΩ insulation and <1pF capacitance; sparks over at 1000V ±30% DC (dv/dt = 100V/s) or 1800V impulse (1kV/μs), diverting up to 1.0kA of 8/20μs surge current to the other terminal. |
| 2 | T2 | passive | Gas discharge tube terminal 2. Symmetrical, non-polarized electrode of the two-terminal SMD gas arrester; connect to ground or to the protected line. Electrically identical to T1; conducts the surge current when the tube fires at the specified spark-over voltage. |
