Vishay Intertech · Diodes - General Purpose · SOD-80
BA679-GS18 from Vishay Intertech, in a SOD-80. 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 black cathode band; the diode conducts forward current (IF max 50 mA) from anode to cathode and withstands VR max 30 V. |
| 2 | A | passive | Anode terminal of the single PIN diode; forward current IF is limited to 50 mA continuous and differential resistance is controlled by this bias current. |
