Leading Power Semiconductor Manufacturer

Power Rectifier Diode Д Series (D Series)

Power Rectifier Diodes LJ-MD, also known as stud mount rectifier diodes, are versatile components designed to convert DC and AC currents up to 500A at frequencies of up to 500 Hz, accommodating voltages ranging from 300 to 3000V, depending on the specific series. These diodes are available in various types, ranging from 100A to 500A, providing a wide range of options to suit different applications. The technical specifications, part numbering guide, polarity information, dimensions, and recommended cooling solutions are provided to facilitate seamless integration into diverse systems. Additionally, our diodes feature a standardized housing and a sealed ceramic enclosure, ensuring reliable performance and protection against environmental factors. To enhance thermal management, air and water heat sinks are employed, along with heat-conducting paste during assembly, ensuring efficient heat dissipation and prolonged lifespan.

Rectifying diodes serve as essential components in power switches, offering low static and dynamic losses, high VRRM values, and robust resistance to thermal and electric cycling. Our diodes have been extensively utilized across various industries, demonstrating their versatility and reliability. We stand behind the quality of our products, offering a guarantee and providing certificates of conformity upon request. The pricing of our power rectifier diodes is determined by factors such as voltage class, quantity, delivery terms, manufacturer, country of origin, and payment method, ensuring transparency and flexibility to meet diverse customer needs.
