1.5SMC480CA from Littelfuse, in a DO-214AB. 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 | A1 | passive | Bi-directional terminal 1 of the 1.5SMC480CA (VR 408 V, VBR 456-504 V at 1 mA, VC 658 V at 3.1 A Ipp); polarity-independent, no cathode band. |
| 2 | A2 | passive | Bi-directional terminal 2 of the 1.5SMC480CA (VR 408 V, VBR 456-504 V at 1 mA, VC 658 V at 3.1 A Ipp); polarity-independent, no cathode band. |
