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.

Features:
- Simplifies Logic Control of 110VAC Power
- Zero Voltage Crossing
- High Breakdown Voltage: VDRM = 250V Min
- High Isolation Voltage: VISO = 7500V Min
- dv/dt of 100V/μs Typ
