BYG21M-E3-FS from FUXINSEMI, 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 | cathode | passive | Cathode end, marked by the color band on the package; the device is rated for a maximum repetitive peak reverse voltage of 1000 V and an average forward current of 1.5 A. |
| 2 | anode | passive | Anode end, opposite the color band; forward current flows from this pin to the cathode (pin 1), with a 30 A peak forward surge current rating for 10 ms single half sine-wave. |
