# PESDNC2FD3V3B

**Shanghai Prisemi Elec** · ESD And Surge Protection (TVS/ESD) · DFN1006-2L

PESDNC2FD3V3B from Shanghai Prisemi Elec, in a DFN1006-2L. 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 | Pin 1 | passive | One of the two terminals of the bidirectional ESD protector, labelled Pin 1 in the bottom view and circuit diagram, protecting one bidirectional line with a 3.3 V reverse stand-off voltage (VRWM). The datasheet does not state a separate function for this terminal. |
| 2 | Pin 2 | passive | The other of the two terminals of the bidirectional ESD protector, labelled Pin 2 in the bottom view and circuit diagram, protecting one bidirectional line with a 3.3 V reverse stand-off voltage (VRWM). The datasheet does not state a separate function for this terminal. |
