DESCRIPTION
• Zero voltage crossing detector
The IL410 and IL4108 consists of a GaAs IRLED optically
coupled to a photosensitive zero crossing TRIAC network.
The TRIAC consists of two inverse parallel connected
monolithic SCRs. These three semiconductors are
assembled in a six pin dual in-line package.
High input sensitivity is achieved by using an emitter
follower phototransistor and a cascaded SCR predriver
resulting in an LED trigger current of less than 2 mA (DC).
The use of a proprietary dV/dt clamp results in a static dV/dt
of greater than 10 kV/ms. This clamp circuit has a MOSFET
that is enhanced when high dV/dt spikes occur between
MT1 and MT2 of the TRIAC. When conducting, the FET
clamps the base of the phototransistor, disabling the first
stage SCR predriver.
The zero cross line voltage detection circuit consists of two
enhancement MOSFETS and a photodiode. The inhibit
voltage of the network is determined by the enhancement
voltage of the N-channel FET. The P-channel FET is enabled
by a photocurrent source that permits the FET to conduct
the main voltage to gate on the N-channel FET. Once the
main voltage can enable the N-channel, it clamps the base
of the phototransistor, disabling the first stage SCR
predriver.
The 600 V, 800 V blocking voltage permits control of off-line
voltages up to 240 VAC, with a safety factor of more than
two, and is sufficient for as much as 380 VAC.
The IL410, IL4108 isolates low-voltage logic from 120 VAC,
240 VAC, and 380 VAC lines to control resistive, inductive, or
capacitive loads including motors, solenoids, high current
thyristors or TRIAC and relays.

TRIGGER CURRENT VS. TEMPERATURE AND VOLTAGE
The trigger current of the IL410, 4108 has a positive
temperature gradient and also is dependent on the terminal
voltage as shown as the fig. 11.
For the operating voltage 250 VRMS over the temperature
range - 40 °C to 85 °C, the IF should be at least 2.3 x of the
IFT1 (2 mA, max.).
Considering - 30 % degradation over time, the trigger
current minimum is IF = 2 x 2.3 x 130 % = 6 mA

In order to achieve control with certain inductive loads of
power factors is less than 0.8, the rate of rise in voltage
(dV/dt) must be limited by a series RC network placed in
parallel with the power handling triac. The RC network is
called snubber circuit. Note that the value of the capacitor
increases as a function of the load current as shown in fig. 13.
Failed to keep on
As a zero-crossing phototriac, the commutating dV/dt
spikes can inhibit one half of the TRIAC from keeping on If
the spike potential exceeds the inhibit voltage of the zero
cross detection circuit, even if the LED drive current IF is on.
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. 14 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.

If the commutating dV/dt is too high, more than its critical

The voltage across the triac will rise rapidly at the time the
current through the power handling triac falls below the
holding current and the triac ceases to conduct. The rise
rate of voltage at the current commutation is called
commutating dV/dt. There would be two potential problems
for ZC phototriac control if the commutating dV/dt is too
high. One is lost control to turn off, another is failed to keep
the triac on.

APPLICATIONS
Indirect switching operation:
Direct switching operation:
The IL410, IL4108 isolated switch is mainly suited to control
synchronous motors, valves, relays and solenoids. Fig. 15
shows a basic driving circuit. For resistive load the snubber
circuit RS CS can be omitted due to the high static dV/dt
characteristic.
The IL410, IL4108 switch acts here as an isolated driver and
thus enables the driving of power thyristors and power triacs
by microprocessors. Fig. 16 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 IL410, IL4108. The resister RG is needed
only for very sensitive thyristors or triacs from being
triggered by noise or the inhibit current.
