# PESDNC2FD12VB

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

PESDNC2FD12VB 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 | I/O 1 | passive | One terminal of the bidirectional ESD protector, placed directly on the signal trace; VRWM 12V, VBR 14V min at 1mA, IEC61000-4-2 ±30kV air/contact. |
| 2 | I/O 2 | passive | Other terminal of the bidirectional ESD protector, connected to ground or the return path; the device is symmetric so the terminals are interchangeable, with VC 22V at IPP=1A and 27V at IPP=4A. |
