BYG22D

LGE · Avalanche Diodes · SMA

BYG22D from LGE, in a SMA. 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; reverse-blocking up to VRRM of 200 V for BYG22D.
2 A passive Anode, the end opposite the color band; average forward current up to 2.0 A with VF of 1.1 V at IF = 2.0 A.
