Vishay Intertechnology, Inc., worldwide leader and manufacturer of semiconductors and materials, has announced its expansions of its “VOW Widebody family of high-isolation optocouplers with a new series of high-speed devices capable of 1 MBd and 10 MBd data rates. Designed to increase reliability in high-voltage alternative energy and industrial applications, the VOW135, VOW136, VOW137, and VOW2611 provide a VIOTM of 8000 V, VIORM of 1414 V, and offer an external creepage distance of greater than 10 mm,” the company says.
“The VOW135, VOW136, VOW137, and VOW2611 are designed to isolate low- to high-voltage circuits in alternative energy systems such as solar inverters and in industrial applications such as motion and motor control and welding equipment. Eliminating the need for expensive conformal-coated solutions, the VOW Widebody devices allow designers to meet domestic and international safety agency requirements at a low cost and with a small form factor.”
Other features of the VOW135, VOW136, VOW137, and VOW2611 include a a GaAIAs infrared emitting diode, a photo detector, increased robustness, higher safety, an internal shield, high creepage distance, and lower levels of delay. They also conform to Vishay’s “Green Standards.”
“The VOW135 and VOW136 offer common mode transient immunity of 1000 V/μs and high- and low-level propagation delay of less than 2 µs at a data rate of 1 MBd. VOW137 and VOW2611 devices provide a data rate of 10 MBd and boost common mode transient immunity up to 40000 V/μs while keeping high- and low-level propagation delay at less than 100 ns and high pulse width distortion less than 40 ns.”
