General Description
The MOC301XM and MOC302XM family of triac driver devices are optically isolated. A GaAs infrared emitting diode and a light-activated silicon bilateral switch that behaves like a triac are used in these devices. They're made to connect electronic controllers to power triacs in order to regulate resistive and inductive loads in 115 VAC applications.

Construction
Where to Use
Triacs can be widely used in industries, transportation, household appliances, and other fields to achieve AC voltage regulation, motor speed regulation, AC switches, automatic street lights turning on and off, temperature control, desk lamp dimming, stage dimming, and other functions. It is also used in the solid-state relay (SSR) and solid-state contactor circuits.
How to Use
The MOC30XX series random phase (non-zero crossing) bidirectional thyristor driver is composed of aluminum gallium arsenide infrared LED, which is optically coupled to the silicon detector chip. The two chips are assembled in a 6-pin DIP package, providing 7.5KVAC (PEAK) insulation between the LED and the output detector. These output detector chips are designed to drive triacs to control the load on the 115 and 220V AC power lines. The detector chip is a complex device with the same function as a small triac, generating the signals required to drive the gate of a larger triac (such as Fairchild’s FKPF12N80). MOC30XX triacs can control higher power triacs with the least number of additional components.
Guidelines
Thyristor components have many advantages, but they have poor overload capacity, short-term over-current, and over-voltage will cause component damage. Therefore, in order to ensure the normal operation of the component, conditions are required (1) The applied voltage is allowed to exceed the forward turning voltage, otherwise The control pole will not work; (2) The on-state average current of the thyristor is generally 1.5 to 2 times the maximum current from a safety point of view.
