Models with Externally Attached Heat Sinks
Heat Resistance Rth (Junction/SSR Back
Surface)
Heat Resistance of Heat Sinks
Note:
If a commercially available heat sink is used, use one that has
a heat resistance equal to or lower than a standard OMRON
Heat Sink.
Inrush Current Resistance: Non-repetitive
Keep the inrush current to below the inrush current resistance value (i.e., below the broken line) if it occurs repetitively.

G3PE-225B-3H
G3PE-525B-3H
Note:
The heat sink area is the combined
area of all surfaces of the heat sink
that radiate heat.
For the G3PE-525B-3H, when a
current of 18 A flows through the SSR
at 40
°
C, the graph shows that a heat
sink area of about 2,500 cm
2
would
be required. Therefore, if the heat
sink is square, one side of an
aluminum plate in the heat sink must
be 36 cm or longer (
√
2,500 (cm
2
)/2 =
36 cm (rounded to a whole number)).
