■ Design Considerations

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.

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=0.022µF 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 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 0.5N•m.

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.
