Leading Power Semiconductor Manufacturer

Single-Phase Rectifier Bridge Module MDQ

Introducing our line of Rectifier Bridge Modules, including the Three-Phase MDS and Single Phase MDQ models. These modules feature electrical insulation between the chip and the base plate, a maximum AC voltage of 2500V, and international standard packaging for ease of use. The use of vacuum and hydrogen gas protection welding technology ensures high quality and reliability. With a maximum operating junction temperature of 150°C and low forward voltage drop, our Rectifier Bridge Modules offer superior performance and reliability in a variety of applications.
