# SLVU2.8-4N

**BORN** · ESD And Surge Protection (TVS/ESD) · SOP-8

SLVU2.8-4N from BORN, in a SOP-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 | IO1_A | passive | Line 1 protected side, internally tied to pin 3, forming one terminal of the first bidirectional TVS pair (opposite terminal pins 2,4). |
| 2 | IO1_B | passive | Line 1 opposite terminal, internally tied to pin 4, of the first bidirectional TVS pair (opposite pins 1,3); 2.8V reverse stand-off. |
