Helps protecting solid-state relays against voltage transient due to the

inductive effect of lines and loads.

u

Fly wheel diode (D2), with fast response, low on-state voltage drop and

connection polarity free, mounted on the metal base plate to be cooled

by a heatsink for high switching frequency applications (PWM)
