PESDUC2FD3V3B 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 ESD clamp, rated for a 3.3 V peak reverse working voltage (VRWM) with a junction capacitance of 0.2 pF typical and 0.35 pF maximum at VR = 0 V, 1 MHz. |
| 2 | Pin 2 | passive | The other terminal of the bidirectional ESD clamp, which protects one bidirectional I/O or power line with a 4.8 V minimum breakdown voltage at 1 mA test current. |
