Applications of random phase crossing triac drivers

Posted: 18 Dec 2008 ?? ?Print Version ?Bookmark and Share

Keywords:driver triac? random crossing phase? silicon chip detector?

The MOC30XX family of random phase (non-zero crossing) triac drivers consist of an aluminum gallium arsenide infrared LED, optically coupled to a silicon detector chip. These two chips are assembled in a 6-pin DIP package, providing 7.5KVAC(PEAK) of insulation between the LED and the output detector. These output detector chips are designed to drive triacs controlling loads on 115V and 220V AC power lines. The detector chip is a complex device that functions in the same manner as a small triac, generating the signals necessary to drive the gate of a larger triac such as Fairchild�s FKPF12N80. The MOC30XX triacs are capable of controlling larger power triacs with a minimum number of additional components.
