SL520B 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, identified by the white band on the package body; the SL520B is rated 200 V VRRM/VDC and 5.0 A average forward current. |
| 2 | A | passive | Anode, the terminal opposite the white-band cathode end; forward voltage drop is 0.85 V max at IF = 5.0 A (TA = 25℃). |
