ISE, Inc.
This relay is designed for use
in applications in which it is
exposed to high surge condi-
tions. Care must be taken to
ensure
when the relay is to be used at
high sustained currents. Ade-
quate electrical connection
between relay terminals and
cable must be ensured.

tant. It is essential that the user
makes sure that cooling is ad-
equate and that the maximum
junction temperature of the re-
lay is not exceeded.
If the heatsink is placed in a
small closed room, control
panel or the like, the power
dissipation can cause the
ambient temperature to rise.
The heatsink is to be cal-
culated on the basis of the
ambient temperature and the
increase in temperature.

Direct bonding
In the design of the output
power semiconductor direct
bonding of the copper layer
and the ceramic substrate has
been applied. This is to en-
sure uninhibited heat transfer
and
strength.
The relay has been designed
for applications requiring lar-
ge numbers of load cycles.
Power dissipation
The power dissipation for in-
termittent use is calculated ac-
cording to the following for-
