Description
The MOC3051M and MOC3052M consist of a GaAs
infrared emitting diode optically coupled to a non-zero-
crossing silicon bilateral AC switch (triac). These devices
isolate low voltage logic from 115 V
AC
and 240 V
AC
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 performance
of inductive loads.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only. T

3. All devices are guaranteed to trigger at an I

operating I
F
lies between maximum I

(15 mA for MOC3051M, 10 mA for MOC3052M) and absolute maximum

Figure 5 shows the increase of the trigger current when
the device is expected to operate at an ambient temper-
ature below 25°C. Multiply the normalized I

shown on
this graph with the data sheet guaranteed I

cross detector. The same task can be accomplished by a
microprocessor which is synchronized to the AC zero
crossing. The phase controlled trigger current may be a
very short pulse which saves energy delivered to the
input LED. LED trigger pulse currents shorter than
100 µs must have an increased amplitude as shown on
Figure 6. This graph shows the dependency of the trig-
ger current I
FT
versus the pulse width can be seen on
the chart delay t(d) versus the LED trigger current.
I
FT
in the graph I
FT
versus (PW) is normalized in respect
to the minimum specified I
FT
for static condition, which is
specified in the device characteristic. The normalized I
FT
has to be multiplied with the devices guaranteed static
trigger current.
Example:
Guaranteed I
FT
= 10 mA, Trigger pulse width PW = 3 µs
I
FT
(pulsed) = 10 mA x 5 = 50 mA
Phase Control Considerations
LED Trigger Current versus PW (normalized)
Random Phase Triac drivers are designed to be phase
controllable. They may be triggered at any phase angle
within the AC sine wave. Phase control may be accom-
plished by an AC line zero cross detector and a variable
pulse delay generator which is synchronized to the zero
