DESCRIPTION
The MOC3051-M and MOC3052-M consist of a AlGaAs infrared emitting diode optically coupled to a non-zero-crossing silicon
bilateral AC switch (triac). These devices isolate low voltage logic from 115 and 240 Vac lines to provide random phase control of
high current triacs or thyristors. These devices feature greatly enhanced static dv/dt capability to ensure stable switching perfor-
mance of inductive loads.

Applications
AC SINE
In Phase control applications one intends to be able to control
each AC sine half wave from 0 to 180 degrees.Turn on at zero
degrees means full power and turn on at 180 degree means
zero power. This is not quite possible in reality because triac
driver and triac have a fixed turn on time when activated at
zero degrees. At a phase control angle close to 180 degrees
the driver’s turn on pulse at the trailing edge of the AC sine
wave must be limited to end 200 ms before AC zero cross as
shown in Figure 5. This assures that the triac driver has time
to switch off. Shorter times may cause loss of control at the
following half cycle.

Triac drivers with good noise immunity (dv/dt static) have inter-
nal noise rejection circuits which prevent false triggering of the
device in the event of fast raising line voltage transients. Induc-
tive loads generate a commutating dv/dt that may activate the
triac drivers noise suppression circuits. This prevents 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 9. Delay Time, t(d), and Fall Time, t(f),
vs. LED Trigger Current
The triac driver’s turn on switching speed consists of a turn on
delay time t(d) and a fall time t(f). Figure 9 shows that the delay
time depends on the LED trigger current, while the actual
trigger transition time t(f) stays constant with about one micro
second.

The delay time is important in very short pulsed operation
because it demands a higher trigger current at very short

The turn on transition time t(f) combined with the power triac’s
turn on time is important to the power dissipation of this

The new random phase triac driver family MOC3052-M and
MOC3051-M are very immune to static dv/dt which allows
snubberless operations in all applications where external
generated noise in the AC line is below its guaranteed dv/dt
withstand capability. For these applications a snubber circuit is
not necessary when a noise insensitive power triac is used.
Figure 11 shows the circuit diagram. The triac driver is directly
connected to the triac main terminal 2 and a series Resistor R
which limits the current to the triac driver. Current limiting
resistor R must have a minimum value which restricts the
current into the driver to maximum 1A.

The power dissipation of this current limiting resistor and the
triac driver is very small because the power triac carries the
load current as soon as the current through driver and current
limiting resistor reaches the trigger current of the power triac.
The switching transition times for the driver is only one micro
second and for power triacs typical four micro seconds.
