SMBJ6V8CA from YFW, in a DO-214AA(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 | 1 | passive | Terminal 1 of the 2-lead SMB package; the datasheet pinning lists 1 as Cathode for unipolar parts, and the bipolar (CA) symbol is shown with both terminals equivalent. |
| 2 | 2 | passive | Terminal 2 of the 2-lead SMB package; the datasheet pinning lists 2 as Anode for unipolar parts, and the bipolar (CA) symbol is shown with both terminals equivalent. |
