- Helps protecting solid-state relays against voltage transient due to the inductive
effect of lines and loads.
- 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)
- Decoupling capacitor (C1), connection polarity free and non polarized (polyester)
equipped with a discharging resistor
- SSR voltage clamping function (D1) not included therefore more adapted to
SOM0 DC SSR range (SSR with built-in voltage protection D1)
