SZP6SMB62CAT3G
Littelfuse · TVS · SMB
SZP6SMB62CAT3G 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 | Terminal 1 is labeled Cathode on the SMB part-marking diagram for uni-directional devices, while the datasheet's polarity note says the color band denotes cathode only for unidirectional components, so this bi-directional CA part has no stated polarity. |
| 2 | Anode | passive | Terminal 2 is labeled Anode on the SMB part-marking diagram for uni-directional devices, while the datasheet's polarity note says the color band denotes cathode only for unidirectional components, so this bi-directional CA part has no stated polarity. |
