SZP6SMB36CAT3G from Littelfuse, in a SMB. 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 | Cathode | passive | Cathode terminal of the SMB package, labelled 'Cathode' on the part marking diagram; the datasheet states the color band denotes the cathode only for unidirectional components. |
| 2 | Anode | passive | Anode terminal of the SMB package, labelled 'Anode' on the part marking diagram. |
