SS54L 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 SS54L is rated for 40 V VRRM/VDC and 5.0 A average forward current. |
| 2 | A | passive | Anode; the datasheet gives a maximum forward voltage of 0.45 V at IF = 5.0 A and TA = 25℃. |
