Vishay Intertechnology Inc. has introduced its CAT IV high-voltage isolation optocouplers, which are available in surface-mount packages.
Certified by international safety regulatory agency VDE, the CNY64ST and CNY65ST series products offer long creepage distances and a high isolation test voltage to protect workers and equipment used in high-voltage environments, such as wind turbine and solar power grid connections, according to Vishay.
The CNY64ST and CNY65ST complement the CNY6x series of through-hole devices already available. The CNY6x series of CAT IV optocouplers protects equipment and people from being damaged or injured by a high-voltage spike or transient of up to 12,000 V and a recurring peak voltage of 1,450 VPEAK while allowing data to pass from the high-voltage side to low-voltage monitoring equipment, Vishay explains.
