VSSA310S-M3 from Vishay Intertech, in a SMA(DO-214AC). 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, the end marked by the color band on the DO-214AC (SMA) package; the diode is rated for VRRM 100 V and 3.0 A average forward current. |
| 2 | A | passive | Anode terminal of the single-die Trench MOS Schottky rectifier, opposite the cathode band end of the DO-214AC (SMA) package. |
