... DIP Random-Phase Optoisolators Triac Drivers (600 Volts Peak) The MOC3051 Series consists of a GaAs infrared LED optically coupled to a non–Zero–crossing silicon bilateral AC switch (triac). The MOC3051 Series isolates low voltage logic from 115 and 240 Vac lines to provide random phase control of high current triacs or thyristors ...

... Holding Current, Either Direction 1. Test voltage must be applied within dv/dt rating. 2. All devices are guaranteed to trigger value less than or equal to max Therefore, recommended operating I F lies between max for MOC3051 for 3052 and absolute max I F (60 mA). TYPICAL ELECTRICAL CHARACTERISTICS 2 1.8 ...

... AC sine wave must be limited to end 200 s 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. MOC3051 MOC3052 3 ...

... MOC3051 MOC3052 Basic Triac Driver Circuit The new random phase triac driver family MOC3052 and MOC3051 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 ...
