Vishay Intertechnology has introduced two high-speed analogue optocouplers in the industry-standard SOP5 package, saving up to 75% in PCB space compared to a DIP8 SMD package. The VOM452T and VOM453T feature a baud rate of 1MBd in a low-profile package with a height of 2mm. They also feature a short propagation delay of 1µs, which is critical for applications requiring faster switching times than standard phototransistor optocouplers. The 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 or automation controllers, which have an operator interface. 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 SOP5 package provides 3750VRMS of voltage isolation. The VOM452T is rated for 1kV/µs common mode noise immunity while the VOM453T is rated for 15kV/µs. Electronica: Hall A5: stand 143
