SMD3216-300N

hongjiacheng · Gas Discharge Tube Arresters (GDT) · 1206

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.
