6-Pin DIP Random-Phase
Optoisolators Triac Drivers
(600 Volts Peak)
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. The MOC3051 Series features greatly
enhanced static dv/dt capability to ensure stable switching performance of
inductive loads.
Recommended for 115/240 Vac(rms) Applications:
Preferred devices are Motorola recommended choices for future use and best overall value.
