One Cycle Surge Current
The values shown by the solid line are for non-repetitive inrush currents.
Keep the inrush current below the values shown by the dotted line if it occurs repetitively.

Load current (A)
Thermal Resistance Rth (Back of
Junction SSR) (Examples)
Note: The heat sink area refers to the combined area
of the sides of the heat sink that radiate heat.
For example, when a current of 18 A is allowed
to flow through the SSR at 40°C, the graph
shows that the heat sink area is about 450 cm2.
Therefore, if the heat sink is square, one side of
the heat sink must be 15 cm ( 450 (cm2)/2 ) or
longer.

Note: When using a commercially available heat sink, use one with a
thermal resistance equal to or less that the OMRON Heat Sink.
