B72500T0140K060 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 of the bidirectional varistor (CT0603K14G, VRMS,max 14 V, VDC,max 18 V); the part is symmetric and connects in parallel with the circuit to be protected. |
| 2 | 2 | passive | Second terminal of the bidirectional varistor, interchangeable with terminal 1; recommended pad 1.00 mm x 1.00 mm with 1.00 mm gap on a 1.6 x 0.8 mm body. |
