Vishay Semiconductors Optocoupler, Phototriac Output, Zero
Crossing, Very Low Input Current
This hold-off condition can be eliminated by using a snubber
and also by providing a higher level of LED drive current. The
higher LED drive provides a larger photocurrent which
causes the triac to turn-on before the commutating spike
has activated the zero cross detection circuit. Fig. 10 shows
the relationship of the LED current for power factors of less
than 1.0. The curve shows that if a device requires 1.5 mA
for a resistive load, then 1.8 times (2.7 mA) that amount
would be required to control an inductive load whose power
factor is less than 0.3 without the snubber to dump the
spike.

APPLICATIONS
Direct switching operation:
The IL4116, IL4117, IL4118 isolated switch is mainly suited
to
control
synchronous
motors,
valves,
relays
and
solenoids. Fig. 11 shows a basic driving circuit. For resistive
load the snubber circuit RS CS can be omitted due to the
high static dV/dt characteristic.

Indirect switching operation:
The IL4116, IL4117, IL4118 switch acts here as an isolated
driver and thus enables the driving of power thyristors and
power triacs by microprocessors. Fig. 12 shows a basic
driving circuit of inductive load. The resister R1 limits the
driving current pulse which should not exceed the maximum
permissible surge current of the IL4116, IL4117, IL4118.
The resister RG is needed only for very sensitive thyristors or
triacs from being triggered by noise or the inhibit current.
