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.

Note 2. 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).
