connected to the line by transformers and which are not mechani-
cally interrupted.
In such cases as well as in applications with a resistive load the cor-
responding protective circuits can be neglected.
Control And Turn-On Behavior
The trigger current of the IL410/ IL4108 has a positive
temperature gradient. The time which expires from
applying the control current to the turn-on of the load
current is defined as the trigger delay time (t
the whole this is a function of the overdrive meaning
the ratio of the applied control current versus the trig-
ger current (I
corresponds to that of the individual trigger current of
IL410/4108 turn-on delay times amounts to a few mil-
liseconds only. The shortest times of 5.0 to 10 s can
be achieved for an overdrive greater or equal than 10.
The trigger delay time rises with an increase in tem-
perature.
For very short control current pulses (t
correspondingly higher control current must be used.
Only the IL410/ IL4108 without zero voltage switch is
suitable for this operating mode.
Zero Voltage Switch
The IL410/ IL4108 with zero voltage switch can only
be triggered during the zero crossing the sine AC volt-
age. This prevents current spikes, e.g. when turning-
on cold lamps or capacitive loads.
Applications
Direct switching operation: The IL410/ IL4108 switch
is mainly suited to control synchronous motors,
valves, relays and solenoids in Grätz circuits. Due to
the low latching current (500 A) and the lack of an
RC circuit at the output, very low load currents can
easily be switched.
Indirect switching operation: The IL410/ IL4108
switch acts here as a driver and thus enables the driv-
ing of thyristors and triacs of higher performance by
microprocessors. The driving current pulse should not
exceed the maximum permissible surge current of the
IL410/ IL4108. For this reason, the IL410/ IL4108
without zero voltage switch often requires current lim-
iting by a series resistor.
The favorably low latching current in this operating
mode results in AC current switches which can handle
load currents from some milliamperes up to high cur-
rents.

Application Note
• Over voltage protection: A voltage-limiting varistor
(e.g. SIO VS05K250) which directly connected to the
IL410/ IL4108 can protect the component against
overvoltage.
