SMD4532-200M from DOWO, 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 terminal 1; device conducts bidirectionally when voltage across terminals exceeds DC breakdown voltage of 160-240 V (200 V nominal at 100 V/s) and clamps impulse spark-over voltage to ≤650 V at 1 kV/µs; rated 2000 A (8/20 µs, 2×) and 6 kV (10/700 µs, 5×); insulation resistance ≥1 GΩ (DC 100 V); capacitance ≤1 pF (1 MHz). |
| 2 | A2 | passive | Gas discharge tube terminal 2; electrically symmetric with terminal 1; same breakdown, surge, and insulation ratings; operating temperature -40 to +90 °C. |
