Leading Power Semiconductor Manufacturer

The Non Isolated Diode Module MDY is the perfect solution for high-performance and demanding applications. Featuring a full pressure junction structure and conforming to international packaging standards, this module is designed with a common electrode on the flooring. With excellent temperature characteristics and power cycling capabilities, it can operate at a maximum junction temperature of 150°C. It has a voltage rating of up to 2500V and a positive forward voltage drop, making it ideal for tough applications. Forced air cooling is required for modules under 350A, while modules exceeding 400A can use either air or water cooling. Our module is straightforward to install and maintain, and uses vacuum hydrogen gas protected welding technology for maximum reliability. Trust the Non Isolated Diode Module MDY to deliver superior performance and reliability for your application.
