(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. 3.8mm MIN. 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 rectangu- lar waveform and this results may not make a device turn off. ●
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. ●
