# LESD8D3.3CAT5G

**LRC** · ESD And Surge Protection (TVS/ESD) · SOD-882

LESD8D3.3CAT5G from LRC, in a SOD-882. 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 | 1 | passive | One terminal of the bidirectional ESD protection diode, which is rated for a working peak reverse voltage of 5.0 V max and protects against IEC 61000-4-2 ESD at ±25 kV per the maximum ratings table. |
| 2 | 2 | passive | The other terminal of the bidirectional ESD protection diode, which is interchangeable with pin 1 because the device has no polarity and is rated for a working peak reverse voltage of 5.0 V max. |
