# ESLC0504F

**ElecSuper** · ESD And Surge Protection (TVS/ESD) · SOT-363

ESLC0504F from ElecSuper, in a SOT-363. 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 | bidirectional | Connects to an I/O line that the device protects against ESD and transient voltage events; the datasheet gives no separate electrical limit for this pin. |
| 2 | GND | power_in | Connects to ground, serving as the common reference for the ESD clamps. |
| 3 | IO2 | bidirectional | Connects to an I/O line that the device protects against ESD and transient voltage events; the datasheet gives no separate electrical limit for this pin. |
| 4 | IO3 | bidirectional | Connects to an I/O line that the device protects against ESD and transient voltage events; the datasheet gives no separate electrical limit for this pin. |
| 5 | Vcc | power_in | Connects to the Vcc supply rail; the datasheet gives no voltage limit for this pin, and the 5V working voltage in the features applies to the protected lines. |
| 6 | IO5 | bidirectional | Connects to an I/O line that the device protects against ESD and transient voltage events; the datasheet gives no separate electrical limit for this pin. |
