Leading Power Semiconductor Manufacturer

Single Diode Module MD for Renewable Industry

Our Single PV Diode Module stands out from the competition thanks to its advanced and superior features. With semiconductor chips designed with an innovative insulated flooring, it can withstand high AC voltages of up to 2500V and adheres to international packaging standards. The full pressure junction structure of our product provides excellent temperature characteristics and power cycling capabilities. Forced air cooling is necessary for modules under 350A, while diode module above 400A can be cooled with either air or water. Our product is easy to install, maintain, and employs the latest vacuum hydrogen gas protected welding technology.
