WILLSEMI Will Semicon · Schottky Diodes · SOD-123
WSB5508L-2 from WILLSEMI Will Semicon, 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 | K | passive | Cathode of the Schottky diode (banded end of the package); VR and VRM are rated 40 V, and average rectified forward current is 1 A. |
| 2 | A | passive | Anode of the Schottky diode; forward voltage is 0.57 V max at IF=1A and peak forward current is 25 A (1 us single pulse). |
