Compact three-phase rectifier bridge with Vrrm up to 1600V

IXYS Corporation has released a new family of fully isolated, fully integrated, three-phase rectifier bridges called GUO. The GUO family has a Vrrm rating from 800 V to 1600 V. The first products are the GUO40-12NO1 and the GUO40-16NO1, both rated at 40A bridge output current when mounted on a heatsink.
The GUO rectifier family is designed and optimized to fulfill all industrial standards and required isolation and creepage distances. The fully isolated package provides an isolation voltage of 2500V. The GUO are packaged in a compact, lightweight and thin outline package providing optimized heat dissipation and ruggedness withstanding in-rush current surge.
"The GUO range from IXYS illustrates a development in response to customer requirements for low cost, high reliability, front end rectification. Competitive solutions currently are not able to withstand the higher input voltages inherent in applications such as air conditioning, motor drives or power supplies," explained Bradley Green, Vice President of International Sales of IXYS. "The three-phase diode bridge rectifier is a standard building block to a high percentage of our power semiconductor customers, and offers a high level of integration. This new GUO family can reduce system cost, improve reliability and also reduce the system size and material usage over previous technologies, making it an eco-friendly solution."
