● 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.
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.)
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.

Please keep 5mm distance as minimum between naked metal portion of SSR and heat sink, and also
between naked metal portion of SSR and bis/nut/washer.
However, please avoid the natural rubber for isolation sheet.
