Groomed for interface applications between low-current dc-control circuits and ac-power loads up to 380V, the EL30XX family of six-pin DIP, random-phase and zero-cross triac driver optocouplers specify an operating temperature range from -55°C to +100°C, reportedly the industry's widest. The family includes 21 different devices with a choice of peak blocking voltages from 250V to 800V. Zero-cross versions of the triac driver optocouplers provide extra protection in the form of a zero-crossing detection circuit connected to the gates of the individual SCRs. This eliminates current surges, reduces EMI, and improves transient immunity. Additionally, the 800V series zero-cross devices provides a wide safety margin for control of off-line voltages to 380V. Other features include trigger currents of 5 mA, 10 mA, and 15 mA. The EL30XX devices are grouped in three random-phase series: EL301X (250V), EL302X (400V), EL305X (600V), and four zero-cross series: EL303X (250V), EL304X (400V), EL306X (600V), and EL308X (800V). Prices range from $0.20 to $0.40 each in production quantities. EVERLIGHT AMERICAS INC., Carrollton, TX. (972) 490-4008.
