CATHODE 2 5 NC* *DO NOT CONNECT (TRIAC SUBSTRATE) 6 1 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 performance of inductive loads.

Multiply the normalized IFT shown this graph with the data sheet guaranteed IFT. Example: TA = -40C, IFT = 10 mA IFT @ -40C = 10 mA x 1.4 = 14 mA sine wave. Phase control may be accomplished by an AC line zero cross detector and a variable pulse delay generator which is synchronized to the zero 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 s must have an increased amplitude as shown on Figure 4. This graph shows the dependency of the trigger current IFT versus the pulse width can be seen on the chart delay t(d) versus the LED trigger current. IFT in the graph IFT versus (PW) is normalized in respect to the minimum specified IFT for static condition, which is specified in the device characteristic. The normalized IFT has to be multiplied with the devices guaranteed static trigger current. Example: Guaranteed IFT = 10 mA, Trigger pulse width PW = 3 s IFT (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.

Minimum Time for LED Turn-Off to Zero Cross of AC Trailing Edge 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.

Inductive 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 8 shows the dependency of the triac drivers IFT versus the reapplied voltage rise with a Vp of 400 V. This dv/dt condition simulates a worst case commutating dv/dt amplitude. It can be seen that the IFT does not change until a commutating dv/dt reaches 1000 V/ms. The data sheet specified IFT is therefore applicable for all practical inductive loads and load factors.

Delay Time, t(d), and Fall Time, t(f), vs. LED Trigger Current 100 MOC3052-M t(delay), t(f) versus IFT 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 trigger pulses. This dependency is shown in the graph IFT versus LED PW. The turn on transition time t(f) combined with the power triac's turn on time is important to the power dissipation of this device. SCOPE IFT VTM EXT.

The mercury wetted relay provides a high speed repeated pulse to the D.U.T. 2. 100x scope probes are used, to allow high speeds and voltages. 3. The worst-case condition for static dv/dt is established by triggering the D.U.T. with a normal LED input current, then removing the current. The variable RTEST allows the dv/dt to be gradually increased until the D.U.T. continues to trigger in response to the applied voltage pulse, even after the LED current has been removed. The dv/dt is then decreased until the D.U.T. stops triggering. RC is measured at this point and recorded. Figure 10.

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. R = Vp AC/ITM max rep. = Vp AC/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. VCC RLED TRIAC DRIVER POWER TRIAC RS MOV CS LOAD AC LINE R CONTROL RET.

AC LINE 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 12 is recommended. Fast transients are slowed by the R-C snubber and excessive amplitudes are clipped by the Metal Oxide Varistor MOV. Triac Driver Circuit for Extremely Noisy Environments, as specified in the noise standards IEEE472 and IEC255-4. Industrial control applications do specify a maximum transient noise dv/dt and peak voltage which is superimposed onto the AC line voltage. In order to pass this environment noise test a modified snubber network as shown in Figure 13 is recommended. Typical Snubber values RS = 33 , CS = 0.01 F MOV (Metal Oxide Varistor) protects triac and driver from transient overvoltages >VDRM max. Figure 12.
