# SLSRV05-4

**Slkor SLKORMICRO Elec** · ESD And Surge Protection (TVS/ESD) · SOT-23-6L

SLSRV05-4 from Slkor SLKORMICRO Elec, in a SOT-23-6L. 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 I/O line (steering diodes to the Vcc rail and GND), 5.0V max reverse working voltage to GND and 0.60-0.80pF capacitance to GND. |
| 2 | GND | power_in | Ground reference connected to the anode of the internal avalanche TVS diode, to which every I/O pin is rated (VRWM 5.0V). |
| 3 | I/O2 | passive | ESD-protected I/O line (steering diodes to the Vcc rail and GND), 5.0V max reverse working voltage to GND and 0.60-0.80pF capacitance to GND. |
| 4 | I/O3 | passive | ESD-protected I/O line (steering diodes to the Vcc rail and GND), 5.0V max reverse working voltage to GND and 0.60-0.80pF capacitance to GND. |
| 5 | VCC | power_in | Protected Vcc line, connected to the top steering-diode rail and the cathode of the internal TVS diode, with a 5V working voltage. |
| 6 | I/O4 | passive | ESD-protected I/O line (steering diodes to the Vcc rail and GND), 5.0V max reverse working voltage to GND and 0.60-0.80pF capacitance to GND. |
