Everlight's Random-Phase and Zero-Cross Triac Driver Optocouplers Feature Industry's Widest Operating Temperature Range (-55 to +100 C)Saturday March 1 6:32 AMEverlight's EL30XX triac driver optocouplers offer an inexpensive alternative to using costly discrete driving circuitry requiring multiple components that consume board space. The zero-cross versions of the triac driver optocouplers provide added protection in the form of a zero-crossing detection circuit connected to the gates of the individual Silicon-Controlled Rectifiers (SCR). This eliminates current surges, reduces electromagnetic interference (EMI) and significantly improves transient immunity (dv/dt). Additionally, the 800 V series of zero-cross devices provides a better safety margin for control of off-line voltages of 380 V. Key features of the EL30XX triac driver optocouplers include: -- Complete portfolio: The triac driver optocouplers are offered with choices of low-trigger currents (5 mA, 10 mA and 15 mA) as well as blocking voltages rated from 250 V to 800 V. These features provide design flexibility depending on the maximum trigger current needed to latch the output, or the blocking voltage required to provide the safety tolerance for control of off-line voltages. -- Surface leadform options: Like all Everlight DIP optocouplers, these devices offer a choice of two surface leadform options (S and S1) depending on package height limitations. The low-profile S1 leadform option (3.9 mm max height) is ideal for height-constrained applications while still offering the same benefits of greater than 7 mm creepage and 5 kV isolation voltage of a DIP-style package. -- Wide operating temperature range (-55 to +100 C) meets the temperature requirements of targeted industrial applications. "Everlight's EL30XX random-phase and zero-cross triac driver optocouplers provide complete isolation when driving triacs that control loads on an AC power line," said Krish Ramdass, Optoelectronics Marketing, Everlight Americas, Inc. "This complete portfolio allows designers to choose from many different devices depending on their specific application requirements." Everlight's EL30XX devices are grouped in three random-phase series: EL301X (250 V), EL302X (400 V), EL305X (600 V) and four zero-cross series: EL303X (250 V), EL304X (400V), EL306X (600 V), EL308X (800 V).
