BYG20D-E3 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 terminal, the end marked by the color band; the part is rated for VRRM of 200 V (BYG20D) and IF(AV) of 1.5 A. |
| 2 | A | passive | Anode terminal, the lead opposite the cathode color band; the part is rated for IFSM of 30 A (10 ms half sine-wave). |
