■ Design Considerations
In order for the SSR to turn off, the triggering current (lF) must be 0.1mA or less.
In phase control applications or where the SSR is being by a pulse signal, please ensure that the pulse width
is a minimum of 1ms.
When the input current (IF) is below 0.1mA, the output Triac will be in the open circuit mode. However, if the
voltage across the Triac, VD, increases faster than rated dV/dt, the Triac may turn on. To avoid this situation,
please incorporate a snubber circuit. Due to the many different types of load that can be driven, we can
merely recommend some circuit vales to start with : Cs=0.022F and Rs=47. 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 solenoids.
Following the procedure outlined above should provide sufficient results.
Any snubber or Varistor used for the above mentioned scenarios should be located as close to the main out-
put triac as possible.
The load current should be within the bounds of derating curve. (Refer to Fig.2)
Also, please use the optional heat sink when necessary.
In case the optional heat sink is used and the isolation voltage between the device and the optional heat sink
is needed, please locate the insulation sheet between the device and the heat sink.
When the optional heat sink is equipped, please set up the M3 screw-fastening torque at 0.3 to 0.5Nm.
In order to dissipate the heat generated from the inside of device effectively, please follow the below sugges-
tions.
(a) Make sure there are no warps or bumps on the heat sink, insulation sheet and device surface.
(b) Make sure there are no metal dusts or burrs attached onto the heat sink, insulation sheet and device sur-
face.
(c) Make sure silicone grease is evenly spread out on the heat sink, insulation sheet and device surface.
