S5B from LGE, 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 terminal, marked by the color band on the SMB/DO-214AA body; S5B is rated 400 V VRRM and 5.0 A average forward current. |
| 2 | A | passive | Anode terminal, the end opposite the color band; S5B has 1.15 V maximum forward voltage at 5.0 A. |
