AVR-M1608C220KT2AB from TDK, in a 0603. 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 | 1 | passive | Terminal electrode (Ag/Ni/Sn) of a non-polar varistor, V1mA 22 V (19.8 to 24.2 V), max continuous Vdc 16 V; connect to the protected line. |
| 2 | 2 | passive | Second terminal electrode of the non-polar varistor, interchangeable with the other terminal; typically connected to ground, with clamping voltage 37 V at 2 A (8/20 µs). |
