SL310B 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 100 V (VRRM/VDC) rated reverse-blocking side of the 3.0 A Schottky rectifier. |
| 2 | A | passive | Anode terminal, opposite the white cathode band; forward current up to 3.0 A average with VF max 0.65 V at 25℃ (IF=3.0 A). |
