Leading Power Semiconductor Manufacturer

Our Diode Module MDC features cutting-edge technology designed to meet international standards for high-voltage applications. Our semiconductors provide excellent electrical insulation and can withstand AC voltages up to 2500V. The full-pressure junction structure allows for superior temperature characteristics and power cycling capabilities. Our Diode Module MDC up to 350A requires forced air cooling, while module above 400A can be cooled by either air or water. Installation, use, and maintenance of our product are simple and convenient. We utilize advanced vacuum hydrogen protection welding technology to ensure the highest quality and reliability.
