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

and 240 V

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.

As per DIN EN/IEC 60747-5-5, this optocoupler is suitable for “safe electrical insulation” only within the safety limit data. Compliance with the safety ratings shall be ensured by means of protective circuits.

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. TA = 25°C unless otherwise specified.

triggering of the device in the event of fast raising line voltage transients. 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. In Phase control applications one intends to be able to control each AC sine half wave from 0° to 180°.

The triac driver’s turn on switching speed consists of a turn on delay time t(d) and a fall time t(f). Figure 12 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. 1. 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.

Basic Triac Driver Circuit Triac Driver Circuit for Noisy Environments 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 guaranteed dv/dt withstand capability. For these applications a snubber circuit is not necessary when a noise insensitive power triac is used. Figure 14 shows the circuit diagram.
