# SLLC23T5V2U

**Slkor SLKORMICRO Elec** · ESD And Surge Protection (TVS/ESD) · SOT-23

SLLC23T5V2U from Slkor SLKORMICRO Elec, in a SOT-23. 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 | IO | bidirectional | Connects to the IO data line that the TVS array protects; the datasheet gives no further pin-level limits beyond 'Connect to IO'. |
| 2 | IO | bidirectional | Connects to the IO data line that the TVS array protects; the datasheet gives no further pin-level limits beyond 'Connect to IO'. |
| 3 | GND | power_in | Connects to ground as the common reference for the ESD protection path; the datasheet specifies only 'Connect to GND'. |
