# LESD5D5.0CT1G-ES

**ElecSuper** · ESD And Surge Protection (TVS/ESD) · SOD-523

LESD5D5.0CT1G-ES from ElecSuper, in a SOD-523. 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 | passive | Connects to the protected I/O line (the datasheet protects one bi-directional line), with a reverse stand-off voltage VRWM of 5.0 V and 15 pF typical I/O-to-I/O junction capacitance. |
| 2 | IO2 | passive | Connects to the protected I/O line as the second terminal of the bi-directional protection path, with a reverse stand-off voltage VRWM of 5.0 V and 15 pF typical I/O-to-I/O junction capacitance. |
