■ Description
S102T02 Series and S202T02 Series Solid State
Relays (SSR) are an integration of an infrared emitting
diode (IRED), a Phototriac Detector and a main output
Triac. These devices are ideally suited for controlling
high voltage AC loads with solid state reliability while
providing 3.0kV isolation (V
iso(rms)
) from input to out-
put.

■ Design Considerations
In order for the SSR to turn off, the triggering current (lF) must be 0.1mA or less.
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 used.
Any snubber or Varistor used for the above mentioned scenarios should be located as close to the main output triac as possible.
Particular attention needs to be paid when utilizing SSRs that incorporate zero crossing circuitry.
If 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 process.
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 suggestions.

● Degradation
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 fluctuations 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.
(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.
Silicone 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.
Some 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 rectangular waveform and this results may not make a device turn off.

■ Manufacturing Guidelines
● Soldering Method
Flow Soldering (No solder bathing)
Flow soldering should be completed below 260˚C and within 10s.
Preheating is within the bounds of 100 to 150˚C and 30 to 80s.
Please solder within one time.
Other notices
Please test the soldering method in actual condition and make sure the soldering works fine, since the impact
on the junction between the device and PCB varies depending on the tooling and soldering conditions.

Solvent cleaning :
Solvent temperature should be 45˚C or below. Immersion time should be 3minutes or less.
Ultrasonic cleaning :
The impact on the device varies depending on the size of the cleaning bath, ultrasonic output, cleaning time,
size of PCB and mounting method of the device.
Therefore, please make sure the device withstands the ultrasonic cleaning in actual conditions in advance of
mass production.
Recommended solvent materials :
Ethyl alcohol, Methyl alcohol and Isopropyl alcohol.
In case the other type of solvent materials are intended to be used, please make sure they work fine in actual using conditions since some materials may erode the packaging resin.
● Cleaning instructions
This product shall not contain the following materials.
