SZP6SMB33AT3G 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 unidirectional TVS, identified on the package by the color band; the datasheet states the color band denotes the cathode for unidirectional components. |
| 2 | Anode | passive | Anode terminal of the unidirectional TVS, opposite the cathode band, which clamps transient voltages above the working peak reverse voltage (VRWM = 28.2 V for SZP6SMB33AT3G minimum breakdown, VBR 31.4 V minimum). |
