Toshiba has announced the addition of the TLP290-4 (AC input) and TLP291-4 (DC input) to its family of optocouplers. Suitable for general purpose applications requiring isolation, including power supplies and motor controllers, the optocouplers from Toshiba feature a quad configuration in a double-molded package, a wider creepage distance, improved performance and higher operating temperatures (110 degrees Celsius). The new family of quad couplers can be used in the same socket as Toshiba's popular TLP280-4 and TLP281-4 series of optocouplers, offering higher performance and greater creepage distance for designs in which package height is of a lesser concern.
