| 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/s Typ Absolute Maximum Ratings: (TA = +25C, unless otherwise indicated) Infrared LED Reverse Voltage, VR . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3V Continuous Forward Current, IF . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50mA Total Power Dissipation (TA = +25C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 120mW Derate Above 25C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.33mW/C Output Driver Off-State Output Terminal Voltage, VDRM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 250V Peak Repetitive Surge Current (PW = 100s, 120pps), ITSM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1A Total Power Dissipation (TA = +25C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 150mW Derate Above 25C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.76mW/C Total Device Isolation Surge Voltage (Peak AC Voltage, 60Hz, 1sec Duration, Note 1), VISO . . . . . . . . . . . 7500V Total Power Dissipation (TA = +25C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 250mW Derate Above 25C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2.94mW/C Junction Temperature Range, TJ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 to +100C Ambient Operating Temperature Range, TA . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 to +85C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 to +150C Lead Temperature (During Soldering, 10s), TL . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +260C Note 1 Isolation surge voltage, VISO, is an internal device dielectric breakdown rating.

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).
