For theseapplications, a snubber circuit is not necessary when a noiseinsensitive power triac is used. Figure 7 shows the circuitdiagram. The triac driver is directly connected to the triacmain terminal 2 and a series resistor R which limits thecurrent to the triac driver. Current limiting resistor R musthave a minimum value which restricts the current into thedriver to maximum 1 power dissipation of this current limiting resistor andthe triac driver is very small because the power triac carriesthe load current as soon as the current through driver andcurrent limiting resistor reaches the trigger current of thepower triac.

6 The switching transition times for the driver isonly one micro second and for power triacs typical fourmicro Driver Circuit for Noisy EnvironmentsWhen the transient rate of rise and amplitude are expectedto exceed the power triacs and triac drivers maximumratings a snubber circuit as shown in Figure 8 isrecommended. Fast transients are slowed by the R Csnubber and excessive amplitudes are clipped by the MetalOxide Varistor Driver Circuit for Extremely Noisy EnvironmentsAs specified in the noise standards IEEE472 andIEC255 control applications do specify a maximumtransient noise dv/dt and peak voltage which issuper imposed onto the AC line voltage. In order to pass thisenvironment noise test a modified snubber network asshown in Figure 9 is Trigger Current versus TemperatureRecommended operating LED control current IF liesbetween the guaranteed IFT and absolute maximum 3 shows the increase of the trigger current when thedevice is expected to operate at an ambient temperaturebelow 25 C.

7 Multiply the datasheet guaranteed IFT with thenormalized IFT shown on this graph and an allowance forLED degradation over :IFT = 10 mA, LED degradation factor = 20%IF at 40 C = 10 mA 120% = 15 mALED Trigger Current vs. Pulse WidthRandom phase triac drivers are designed to be phasecontrollable. They may be triggered at any phase anglewithin the AC sine wave. Phase control may beaccomplished by an AC line zero cross detector and avariable pulse delay generator which is synchronized to thezero cross detector. The same task can be accomplished bya microprocessor which is synchronized to the AC zerocrossing. The phase controlled trigger current may be a veryshort pulse which saves energy delivered to the input trigger pulse currents shorter than 100 ms must haveincreased amplitude as shown on Figure 4. This graph showsthe dependency of the trigger current IFT versus the pulsewidth. IFT in this graph is normalized in respect to theminimum specified IFT for static condition, which isspecified in the device characteristic.

8 The normalized IFThas to be multiplied with the devices guaranteed statictrigger :IFT = 10 mA, Trigger PW = 4 msIF (pulsed) = 10 mA 3 = 30 mAMinimum LED Off Time in Phase Control ApplicationsIn phase control applications, one intends to be able tocontrol each AC sine half wave from 0 to 180 . Turn on at0 means full power and turn on at 180 means zero is not quite possible in reality because triac driver andtriac have a fixed turn on time when activated at zerodegrees. At a phase control angle close to 180 the driver sturn on pulse at the trailing edge of the AC sine wave mustbe limited to end 200 ms before AC zero cross as shown inFigure 10. This assures that the triac driver has time to switchoff. Shorter times may cause loss of control at the followinghalf dv/dtCritical rate of rise of off state voltage or static dv/dt is atriac characteristic that rates its ability to prevent falsetriggering in the event of fast rising line voltage transientswhen it is in the off state.

9 When driving a discrete powertriac, the triac driver optocoupler switches back to off stateonce the power triac is triggered. However, during thecommutation of the power triac in application where theload is inductive, both triacs are subjected to fast risingvoltages. The static dv/dt rating of the triac driveroptocoupler and the commutating dv/dt rating of the powertriac must be taken into consideration in snubber circuitdesign to prevent false triggering and commutation , MOC3052M , 7.
