Optoisolator Zero Crossing TRIAC - NTE
Description
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: D Simplifies Logic Control of 110VAC Power D Zero Voltage Crossing D High Breakdown Voltage: VDRM = 250V Min D High Isolation Voltage: VISO = 7500V Min D dv/dt of 100V/µs Typ Absolute Maximum Ratings: (TA = +25°C, unless otherwise indicated) Infrared LED Reverse Voltage, VR .
