The MOC3162 and MOC3163 devices consist of gallium arsenide infrared
emitting diodes optically coupled to monolithic silicon detectors performing the
functions of Zero Voltage Crossing bilateral triac drivers.
They are designed for use with a triac in the interface of logic systems to
equipment powered from 115/240 Vac lines, such as solid–state relays,
industrial controls, motors, solenoids and consumer appliances, etc.

Test voltage must be applied within dv/dt rating.
All devices are guaranteed to trigger at an IF value less than or equal to max IFT. Therefore, recommended operating IF lies between max
IFT (10 mA for MOC3162, 5.0 mA for MOC3163) and absolute max IF (60 mA).
This is static dv/dt. See Figure 9 for test circuit. Commutating dv/dt is a function of the load–driving thyristor(s) only.

This graph shows the increase of the trigger current

temperature below 25°C. Multiply the normalized IFT
shown on this graph with the data sheet guaranteed IFT.
Example:

COMMUTATING dv/dt (V/µs)
Figure 8. LED Trigger Current, IFT, versus dv/dt
IFT versus dv/dt
Triac drivers with good noise immunity (dv/dt stat.) have in-
ternal noise rejection circuits which prevent false triggering of
the device in the event of fast raising line voltage transients.
Inductive loads generate a commutating dv/dt that may acti-
vate the triac driver’s noise suppression circuits. This pre-
vents the device from turning on at its specified trigger
current. It will in this case go into the mode of “half–waving”
of the load. Half–waving of the load may destroy the power
triac and the load.
Figure 8 shows the dependency of the triac drivers IFT ver-
sus the reapplied voltage rise with a Vp of 600 V. This dv/dt
condition simulates a worst case commutating dv/dt ampli-
tude.
It can be seen that the required trigger current IFT changes
with increased dv/dt. Practical loads generate a commutating
dv/dt of less than 50 V/µs. The rate of rise of the commutat-
ing dv/dt is effectively slowed by the use of snubber networks
across the main triac. This snubber is also needed to keep
the commutating dv/dt generated by inductive loads within
the commutating dv/dt ratings of the power triac.

1. The mercury wetted relay provides a high speed repeated pulse
to the D.U.T.
2. 100x scope probes are used, to allow high speeds and voltages.
3. The worst–case condition for static dv/dt is established by
triggering the D.U.T. with a normal LED input current, then
removing the current. The variable RTEST allows the dv/dt to be
gradually increased until the D.U.T. continues to trigger in
response to the applied voltage pulse, even after the LED current
has been removed. The dv/dt is then decreased until the D.U.T.
stops triggering.

LED Trigger Current versus PW (Normalized)
For resistive loads the triac drivers may be controlled by
short pulse into the input LED. This input pulse must be syn-
chronized with the AC line voltage zero–crossing points. LED
trigger pulse currents shorter than 100
µs
must have an in-
creased amplitude as shown on Figure 10. This graph shows
the dependency of the trigger current IFT versus the pulse
width t(PW). IFT in the graph, IFT versus (PW), is normalized
in respect to the minimum specified IFT for static condition,
which is specified in the device characteristic. The normal-
ized IFT has to be multiplied with the device’s guaranteed
static trigger current.
