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

PESDHC2FD4V8UF from Shanghai Prisemi Elec, in a DFN1006-2. 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 | Pin 1 is one of the two terminals of the unidirectional ESD protector, marked as Pin 1 on the DFN1006-2L bottom view and on the tape-and-reel orientation; the datasheet rates the device at a 4.8 V peak reverse working voltage (VRWM) per line. |
| 2 | Pin 2 | passive | Pin 2 is the other terminal of the unidirectional ESD protector, marked as Pin 2 on the DFN1006-2L bottom view; the datasheet specifies 160 pF typical junction capacitance at VR=0 V, f=1 MHz per line. |
