Leading Power Semiconductor Manufacturer

Fast Recovery Rectifier Diode ZK Series

The Fast Recovery Rectifier Diode ZK series is a line of high-performance power semiconductor devices designed and manufactured by our company. These diodes are built using advanced diffusion junction technology and feature a fully enclosed ceramic package and a metal flat-plate structure design, which provide excellent thermal performance and durability. With their ability to handle high surge currents, high-current rating, and double-sided cooling, the ZK series is suitable for a wide range of high-power applications. The ZK series is also unique in its ability to maintain a high-state current when in the off state, ensuring safe operation under high current and high voltage conditions. Offering reliable and efficient performance in a compact and rugged package, the Fast Recovery Rectifier Diode ZK series is the ideal choice for industrial power supplies, welding equipment, and other high-power applications where fast switching and high reliability are critical.
