Basic Triac Driver Circuit
The new random phase triac driver family MOC3052M
and MOC3051M 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 guar-
anteed dv/dt withstand capability. For these applications
a snubber circuit is not necessary when a noise insensi-
tive power triac is used. Figure 14 shows the circuit
diagram. The triac driver is directly connected to the triac
main terminal 2 and a series Resistor R which limits the
Triac Driver Circuit for Noisy Environments
When the transient rate of rise and amplitude are
expected to exceed the power triacs and triac drivers
maximum ratings a snubber circuit as shown in
Figure 15 is recommended. Fast transients are slowed
by the R-C snubber and excessive amplitudes are
clipped by the Metal Oxide Varistor MOV.

current to the triac driver. Current limiting resistor R must
As specified in the noise
standards IEEE472 and
have a minimum value which restricts the current into the
driver to maximum 1 A.
R = Vp AC / I TM max rep. = Vp AC / 1 A
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.
IEC255-4.
Industrial control applications do specify a maximum
transient noise dv/dt and peak voltage which is super-
imposed onto the AC line voltage. In order to pass this
environment noise test a modified snubber network as
shown in Figure 16 is recommended.
