Optocouplers handle wide temperature
range
Everlight's EL30XX triac driver optocouplers offer an inexpensive alternative to using costly discrete driving circuitry requiring multiple components that consume board space.
Everlight Electronics has released a range of of six-pin DIP random-phase and zero-cross triac driver optocouplers offering an operating range of -55 to +100C Encompassing 21 different devices with a choice of peak blocking voltages from 250 to 800V, the EL30XX triac driver optocoupler family provides added design flexibility and significant board space savings in designs interfacing between low-current DC control circuits and AC power loads up to 380V

Optocouplers provide design flexibility
The 4N2X, 4N3X, H11AX, CNY17-X and CNY17F-X phototransistor optocouplers offer flexibility when designing power supplies, programmable logic controllers and general-purpose switching circuits.
LEDs are among the highest flux emitters
New 1 and 3W high-power LEDs deliver high luminosity, long operating life and system efficiency in a broad range of designs.
These include industrial and consumer applications such as refrigerators, dishwashers, temperature controls, air conditioners (HVAC), vending machines, lighting controls, AC motor drives, solid-state relays and solenoid/valve controls.
Everlight'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 800V series of zero-cross devices provides a better safety margin for control of off-line voltages of 380V.
The triac driver optocouplers are offered with choices of low-trigger currents (5, 10 and 15mA) as well as blocking voltages rated from 250 to 800V.
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.
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 is suitable for height-constrained applications while still offering over 7mm creepage and the 5kV isolation voltage of a DIP-style package.
