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

SLESD0502TL 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 | I/O1 | passive | ESD-protected data line I/O; reverse working voltage 5.0V max to GND, 0.2pF typical capacitance I/O to I/O. |
| 2 | I/O2 | passive | Second ESD-protected data line I/O; reverse working voltage 5.0V max to GND, 0.2pF typical capacitance I/O to I/O. |
| 3 | GND | power_in | Ground reference pin connected to the TVS diode common node; breakdown voltage 6.0V min between I/O and GND at 1mA. |
