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)
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 (cm}2_)/2 ) or
longer.
