The FOD420, FOD4208, FOD4216, and FOD4218 devices consist of an infrared light-emitting diode coupled to a hybrid any-phase triac formed using two antiparallel SCRs to form a triac capable of driving a discrete triac. Switches the triac function. The FOD4216 and FOD4218 use a high-efficiency infrared light-emitting diode to provide enhanced trigger sensitivity. These devices use a standard 6-pin dual-inline plug-in (DIP) encapsulation.
