BYG20D-E3

Vishay Intertech · Avalanche Diodes · SMA(DO-214AC)

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).
