SMD3216-300N from hongjiacheng, in a 1206. 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 | 1 | passive | Electrode 1 of the gas discharge tube. Non-polarized; connects across the line to be protected. Fires at ~300 V DC (±30%) to shunt surge current to the other electrode. |
| 2 | 2 | passive | Electrode 2 of the gas discharge tube. Non-polarized counterpart to pin 1; typically tied to protective earth or the return of the protected pair. |
