# PESD5V0L2BT

**Nexperia** · ESD And Surge Protection (TVS/ESD) · SOT-23

PESD5V0L2BT from Nexperia, 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 | K1 | passive | Cathode of the first bidirectional protected line; surge and ESD ratings are measured from pin 1 to pin 3. |
| 2 | K2 | passive | Cathode of the second bidirectional protected line; surge and ESD ratings are measured from pin 2 to pin 3. |
| 3 | CC | passive | Double cathode (common terminal) shared by the two protection diodes, serving as the reference for the pin 1 and pin 2 ratings. |
