Vishay Intertechnology VOW Widebody optocouplers

Vishay Intertechnology is expanding its VOW Widebody family of high-isolation optocouplers with a 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, a VIORM of 1414 V and a high creepage distance of more than 10 mm.

The optocouplers consist of a GaAIAs infrared emitting diode, optically coupled with an integrated photo detector. In addition to the robustness provided by their high safety isolation, the devices feature an internal Faraday shield to provide the high input-to-output noise isolation required by high-power switching applications. Eliminating the need for conformal-coated solutions, they allow designers to meet domestic and international safety agency requirements with a small form factor.

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 40,000 V/μs while keeping high- and low-level propagation delay at less than 100 ns and high pulse width distortion less than 40 ns.
