# PESDUC2FD5VB-ES

**ElecSuper** · Electrostatic And Surge Protection (TVS/ESD) · DFN1006-2L

PESDUC2FD5VB-ES from ElecSuper, 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 | IO1 | bidirectional | Connects to one side of the protected bi-directional I/O line; the datasheet gives only 'Connect to IO' for this pin and no further pin-level limits. |
| 2 | IO2 | bidirectional | Connects to the other side of the protected bi-directional I/O line; the datasheet gives only 'Connect to IO' for this pin and no further pin-level limits. |
