NTE3049 Optoisolator Zero Crossing TRIAC Driver Description: The NTE3049 consists of a gallium arsenide infrared emitting diode optically coupled to a monolithic silicon detector performing the function of a Zero Voltage crossing bilateral triac driver. It is designed for use with a triac in the interface of logic systems to equipment powered from 115 Vac lines, such as teletypewriters, CRTs, printers, motors, solenoids, and consumer appliances.

Test voltage must be applied within dv/dt rating. Note 3. All devices are guaranteed to trigger at an IF value less than or equal to Max IFT. Therefore, recommended operating IF lies between max IFT (15mA) and absolute Max IF (50mA).
