SZP6SMB130AT3G 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 of the uni-directional TVS, marked by the color band on the package and identified by the datasheet as the cathode mark for uni-directional components. |
| 2 | Anode | passive | Anode of the uni-directional TVS, which is the terminal opposite the cathode band, clamping transients at the rated VRWM of 130 V and breakdown VBR of 124 to 137 V. |
