SS22B from Shandong Jingdao Microelectronics, in a SMB. 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 of the SS22B Schottky barrier rectifier; the datasheet states no pin-specific electrical limits beyond the device ratings (VRRM 20 V, IF(AV) 2.0 A). |
| 2 | Anode | passive | Anode terminal of the SS22B Schottky barrier rectifier; the datasheet states no pin-specific electrical limits beyond the device ratings (VRRM 20 V, IF(AV) 2.0 A). |
