NTE3097
Optoisolator
Zero Crossing TRIAC Driver
Description:
The NTE3097 is 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, sole-
noids, and consumer appliances, etc.
