If suf?cient holding current is still ?owing through the
opto-TRIAC, the opto-TRIAC will turn-on and attempt
to carry the power TRIACs load. This situation typically
causes the opto-TRIAC to operate beyond its
maximum current rating, and product and resistor
failures typically result. For this reason, using an opto-
TRIAC to drive a three quadrant “snubberless” power
TRIAC is not recommended.
Power in the 360 ? resistor, when driving a sensitive
gate 4 quadrant power TRIAC:
I GT = 20mA
V GT = 1.5V
DF = 0.6%
P = (I GT +V GT / 330 ? ) 2 x 360 ? x DF
P = (20mA + 1.5 / 330 ? ) 2 *x 360 ? x 0.6% = 1.3mW
A 1/4 watt resistor is more than adequate for both the
360 ? and 330 ? resistors.

The real power in the snubber resistor is based upon
the integral of the power transient present when the
load commutes. A fast commuting transient may allow
a peak current of 4A to 8A in the snubbing ?lter.
For best results, the capacitor should be a non-
polarized AC unit with a low ESR. The 39 ? series
resistor sets a time constant and limits the peak
current. For a resistive load with a power factor near
unity, the commutating transients will be small. This
results in a very small peak current given the 0.01μF
capacitor’s reactance. Normally, for factional horse-
power reactive loads, the resistor found in the snubber
circuit will have a power rating from 1/2W to 2W. The
resistor should be a low inductance type to adequately
?lter the high frequency transients.
