Everlight Electronics Co. Ltd has introduced 4-pin shrink small-outline package phototransistor optocouplers, which have a wide operating temperature range, tight current-transfer-ratio binning, high isolation voltage and high BVceo in an ultralow-profile package.

Dubbed the EL3H7-G series, these optocouplers have a smaller form factor with a 2mm maximum package height and 1.27mm lead pitch to accommodate designs with limited board real estate. They support a wide operating temperature range from -55C to +110C, as well as offer a high isolation voltage of 3750Vrms, minimum creepage distance of 5mm, multiple CTR bins and high breakdown voltage of 80V.

Applications include DC/DC converters, battery chargers, general-purpose switching circuits and programmable controllers.
