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.
4.4mm 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.
Example how to equip optional heat sink for reinforced isolation
1) Case of isolation sheet whose thickness is 0.4mm or more (Viso : 3kV or more)
0.4mm thickness or more
isolation sheet
Heat sink
SSR
2) Case of the use of double isolation sheet (Viso : each 3kV or more)
Isolation sheet
Heat sink
SSR
Please keep 5mm distance as minimum between naked metal portion of SSR and heat sink, and also be-
tween naked metal portion of SSR and bis/nut/washer.
However, please avoid the natural rubber for isolation sheet.
● 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.
