tion, please incorporate a snubber circuit. Due to the many different types of load that can be driven, we can
merely recommend some circuit values to start with : Cs=0.022μF and Rs=47Ω. The operation of the SSR
and snubber circuit should be tested and if unintentional switching occurs, please adjust the snubber circuit
component values accordingly
When making the transition from On to Off state, a snubber circuit should be used ensure that sudden drops
in current are not accompanied by large instantaneous changes in voltage across the Triac.
This fast change in voltage is brought about by the phase difference between current and voltage.
Primarily, this is experienced in driving loads which are inductive such as motors and solenods.
Following the procedure outlined above should provide suffi cient results.
Any snubber or Varistor used for the above mentioned scenarios should be located as close to the main out-
put triac as possible.
All pins shall be used by soldering on the board. (Socket and others shall not be used.)
In general, the emission of the IRED used in SSR will degrade over time.
In the case where long term operation and / or constant extreme temperature fl uctuations will be applied to
the devices, please allow for a worst case scenario of 50% degradation over 5years.
Therefore in order to maintain proper operation, a design implementing these SSRs should provide at least
twice the minimum required triggering current from initial operation.
