Original Press Release:
Everlight's New 4-Pin SSOP Optocouplers Offer Power Supply Designers the Best Combination of Features for Simplifying Designs, Improving System Performance
EL3H7-G series incorporates wide operating temperature range, tight CTR binning, high isolation voltage and high BVceo in an ultra-low-profile package
CARROLLTON, Texas -- August 15, 2008 -- Everlight Electronics Co. Ltd . (TSE: 2393) introduces 4-pin SSOP phototransistor optocouplers with the best available combination of key specifications sought after by power supply designers. These include a low-profile (2 mm) package, high isolation voltage (3750 Vrms), minimum creepage distance (5 mm), wide operating temperature range (-55 °C to +110 °C), multiple current-transfer-ratio (CTR) bins and high breakdown voltage (80 V). The new EL3H7-G series' 11 devices are well suited for use in DC-DC converters, battery chargers, general-purpose switching circuits and programmable controllers. Compared with conventional optocouplers, the EL3H7-G devices offer important features and benefits, including:
Smaller form factor (2 mm max. package height and 1.27 mm lead pitch) accommodates designs with limited board real estate
Higher temperature operation (110 °C vs. 100 °C) improves system reliability
Selectable CTR ranges characterized at low LED currents increase design flexibility
Higher isolation voltage (3750 Vrms vs. 2500 Vrms) improves insulation characteristics
Halogen-free, Pb-free and RoHS-compliant devices meet green environmental initiatives
The combined features provided by Everlight's new EL3H7-G optocouplers allow power supplies to deliver the maximum usable power over a wider temperature range. They also offer a wider margin of safety in applications and provide greater design flexibility for high-end applications.
"Everlight's EL3H7-G series enables power supply designers to now derate their boards up to 110 °C while using an ultra-low-standoff-height device that accommodates low-profile applications," said Krish Ramdass, Optoelectronics Marketing, Everlight Americas, Inc. "Because these 4-pin SSOP optocouplers are capable of reaching higher operating temperatures, they enable DC/DC converters to achieve higher efficiencies and power ratings, as well as improved thermal performance."
