Leading Power Semiconductor Manufacturer

Our Dual PV Diode Module MDA boasts a range of impressive features, including semiconductors with an insulated floor design, capable of withstanding high AC voltages of up to 2500V. Our product conforms to international packaging standards and features a full pressure junction structure, providing excellent temperature characteristics and power cycling capabilities. Modules with current ratings below 350A require forced air cooling, while modules exceeding 400A can use either air or water cooling. In addition, our Dual PV Diode Module MDA is easy to install, maintain, and features vacuum hydrogen gas protected welding technology.
