SS310B50 from JUXING, 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 | K | passive | Cathode, the end marked by the laser band on the DO-214AA molded plastic body. |
| 2 | A | passive | Anode terminal, the end opposite the laser band; the SS310 is rated 100 V DC blocking, 3.0 A average rectified current. |
