SS0540_R1_00301 from PANJIT International, in a SOD-123. 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 | Cathode | passive | Cathode terminal, identified by the color band on the package; the SS0540 variant has a maximum DC blocking voltage of 40 V and a maximum recurrent peak reverse voltage of 40 V. |
| 2 | Anode | passive | Anode terminal of the Schottky barrier diode; the device is rated for a maximum average forward current of 0.5 A at TA=75°C with a 5.5 A peak forward surge current (8.3 ms half-sine). |
