**Shanghai Prisemi Elec** · ESD Protection Devices · DFN1006-2L

PESDNC2FD4V5B 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 terminal of the bidirectional protected line; the per-line limits stated are VRWM 4.5 V and 80 W peak pulse power (tp = 8/20 µs). |
| 2 | Pin 2 | passive | The other terminal of the bidirectional protected line; the datasheet gives no separate function for this pin beyond the bidirectional per-line configuration. |
