SLVU2.8-4BTG from Littelfuse, in a SOIC-8. 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 | 1 | passive | One terminal of the protected line pair 1.3; the datasheet's pinout diagram labels it only as 'Pin 1.3' and gives no separate function name. |
| 2 | 2 | passive | One terminal of the protected line pair 2.4; the datasheet's pinout diagram labels it only as 'Pin 2.4' and gives no separate function name. |
| 3 | 3 | passive | The other terminal of the protected line pair 1.3; the datasheet's pinout diagram labels it only as 'Pin 1.3' and gives no separate function name. |
| 4 | 4 | passive | The other terminal of the protected line pair 2.4; the datasheet's pinout diagram labels it only as 'Pin 2.4' and gives no separate function name. |
| 5 | 5 | passive | One terminal of the protected line pair 5.7; the datasheet's pinout diagram labels it only as 'Pin 5.7' and gives no separate function name. |
| 6 | 6 | passive | One terminal of the protected line pair 6.8; the datasheet's pinout diagram labels it only as 'Pin 6.8' and gives no separate function name. |
| 7 | 7 | passive | The other terminal of the protected line pair 5.7; the datasheet's pinout diagram labels it only as 'Pin 5.7' and gives no separate function name. |
| 8 | 8 | passive | The other terminal of the protected line pair 6.8; the datasheet's pinout diagram labels it only as 'Pin 6.8' and gives no separate function name. |
