Vishay's New VOM452T and VOM453T High-Speed, 1-MBd Analog Optocouplers Feature Common Mode Rejection to 15 kV/us and Isolation Voltage of 3750 VRMS in the Compact SOP-5 Package

MALVERN, PA--(Marketwire - June 14, 2010) -  Vishay Intertechnology, Inc. (NYSE: VSH) is broadening its optoelectronics portfolio with the release of two high-speed analog optocouplers in the industry-standard SOP-5 package, saving up to 75 % in PCB space compared to a DIP-8 SMD package. The new VOM452T and VOM453T feature a baud rate of 1 MBd in a low-profile package with a height of 2.0 mm. They also feature a very short propagation delay of 1 microsecond which is critical for applications requiring faster switching times than standard phototransistor optocouplers.

The VOM452T and VOM453T 1 MBd optocouplers will be used for signal isolation in industrial communication bus lines, such as CANbus, CC-Link, and other serial interfaces. On one side of the bus line, they are connected to programmable logic controllers (PLCs) or automation controllers, which have an operator interface, and on the other side, they are connected to sensors on electrically noisy factory floors. The optocouplers protect operators from electrical shocks and protect the microprocessor within the PLC from being damaged by voltage spikes. The compact SOP-5 package is capable of providing 3750 VRMS of voltage isolation. The VOM452T is rated for 1 kV/microsecond common mode noise immunity while the VOM453T is rated for 15 kV/microsecond.

Samples and production quantities of the new VOM452T and VOM453T are available now, with lead times of six to eight weeks for large orders.
