SS54BQ from Yangzhou Yangjie Elec Tech, in a SMB(DO-214AA). 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, the end marked by the cathode line; the SS54BQ blocks up to 40 V VRRM/VDC. |
| 2 | A | passive | Anode terminal, the end opposite the cathode line; the SS54BQ carries up to 5.0 A average forward current. |
