VS-20BQ030-M3 from Vishay Intertech, 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 | K | passive | Cathode of the single-die Schottky rectifier (VR 30 V max, IF(AV) 2 A); the datasheet's product summary marks the cathode and anode sides but gives no pin numbers. |
| 2 | A | passive | Anode of the single-die Schottky rectifier (VF 0.37 V at 2 A, TJ = 125 °C); the datasheet's product summary marks the cathode and anode sides but gives no pin numbers. |
