The NTE3097 and NTE3097−1 are an optoisolator in a 6−Lead DIP type package and contains a gallium arsenide IRED optically coupled to a monolithic silicon detector performing the function of a Zero Voltage Crossing bilateral TRIAC Driver. This device is designed for use with a TRIAC in the interface of logic systems to equipment powered from 240VAC lines such as solid−state relays, industrial controls, motors, solenoids, and consumer appliances, etc.
