SL515B from NH, 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, marked by the white band on the package; the diode conducts from anode to cathode with VF max 0.82 V at IF = 5.0 A (TA=25℃). |
| 2 | A | passive | Anode; the diode is rated 150 V VRRM and 5.0 A maximum average forward rectified current. |
