**Slkor SLKORMICRO Elec** · ESD And Surge Protection (TVS/ESD) · SOD-323

SLESD3Z5V0C from Slkor SLKORMICRO Elec, in a SOD-323. 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 | Bidirectional TVS terminal 1, connected to the protected I/O line or to ground since the device is symmetric; reverse working voltage 5.0 V max, breakdown 5.6 V min at 1 mA. |
| 2 | 2 | passive | Bidirectional TVS terminal 2, connected to the protected I/O line or to ground since the device is symmetric; reverse working voltage 5.0 V max, breakdown 5.6 V min at 1 mA. |
