CUS10S30 from DOWO, in a SOD-323. 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, the end marked by the color band; reverse blocking voltage VRRM/VDC is 30 V and average forward current is 1 A. |
| 2 | A | passive | Anode, marked '+' on the package drawing; forward voltage is 0.550 V at IF = 1.0 A and 0.875 V at IF = 3.0 A. |
