**Shanghai Prisemi Elec** · Schottky Barrier Diodes (SBD) · DFN1006-2L

PSBD2FD40V1H 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 of the two terminals of the Schottky barrier diode, shown as Pin 1 in the circuit diagram; the text does not state whether it is the anode or cathode, and the device ratings apply (DC reverse voltage 40 V, average rectified current 1 A). |
| 2 | Pin 2 | passive | The other terminal of the Schottky barrier diode, shown as Pin 2 in the circuit diagram; the text does not state whether it is the anode or cathode, and the device ratings apply (DC reverse voltage 40 V, average rectified current 1 A). |
