MVR1812-470G from DOWO, in a 1812. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Varistor terminal A; device clamps at 77 V max (10 A, 8/20 µs pulse) and withstands 500 A peak single-pulse (8/20 µs); bidirectional, symmetric with terminal 2. |
| 2 | B | passive | Varistor terminal B; device clamps at 77 V max (10 A, 8/20 µs pulse) and withstands 500 A peak single-pulse (8/20 µs); bidirectional, symmetric with terminal 1. |
