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=0.022µF 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.

For over voltage protection, a Varistor may be snubber or Varistor used for the above mentioned scenarios should be located as close to the main out-put triac as possible.

Particular attention needs to be paid when utilizing SSRs that incorporate zero crossing the phase difference between the voltage and the current at the output pins is large enough, zero crossing

type SSRs cannot be used. The result, if zero crossing SSRs are used under this condition, is that the SSR

may not turn on and off irregardless of the input current. In this case, only a non zero cross type SSR should

be used in combination with the above mentioned snubber circuit selection 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 No.: D4-A01801EN/8

S108T02 SeriesS208T02 Series(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 ne grease to be used is as follows;

1) There is no aged deterioration within the operating temperature ranges.

2) Base oil of grease is hardly separated and is hardly permeated in the device.

3) Even if base oil is separated and permeated in the device, it should not degrade the function of a device.

Recommended grease: G-746 (Shin-Etsu Chemical Co., Ltd.)

: G-747 (Shin-Etsu Chemical Co., Ltd.)

: SC102 (Dow Corning Toray Silicone Co., Ltd.)

In case the optional heat sink is screwed up, please solder after screwed.

In case of the lead frame bending, please keep the following minimum distance and avoid any mechanical

stress between the base of terminals and the molding resin.

3.8mm of AC electromagnetic counters or solenoids have built-in rectifier such as the diode.

In this case, please use the device carefully since the load current waveform becomes similar with rectangu-lar waveform and this results may not make a device turn off.● DegradationIn general, the emission of the IRED used in SSR will degrade over the case where long term operation and / or constant extreme temperature fluctuations will be applied to

the devices, please allow for a worst case scenario of 50% degradation over ore in order to maintain proper operation, a design implementing these SSRs should provide at least

twice the minimum required triggering current from initial operation.● Standard CircuitS108T02S208T02+VCCR132LoadZSD1V1Tr14SSR1AC LineZS : Surge absorption circuit (Snubber circuit)✩ For additional design assistance, please review our corresponding Optoelectronic Application No.: D4-A01801EN/9
