The 7th-generation fast recovery diodes are mainly matched with IGBT7 modules. Featuring low reverse recovery charge, full-range soft recovery, low voltage spike and low EMI performance, they effectively eliminate the performance bottleneck of IGBT modules caused by traditional diodes. Widely applied in medium and high-voltage power conversion systems, their mainstream voltage ratings cover 650V, 1200V and 1700V, while the 330V grade is specially designed for traction scenarios.

Industrial drive serves as the largest application market. Applied in general inverters for fans, water pumps and air compressors, the devices reduce overall system loss and optimize EMI performance. They are well suited for high-precision servo drives to suppress commutation spikes and lower motor noise under high-frequency operation. For four-quadrant inverters and active front-end (AFE) drives adopted in elevators and lifting equipment, they deliver superior reliability for frequent bidirectional energy feedback operation.

In the new energy sector, these diodes are widely used in photovoltaic inverters, energy storage PCS and wind power converters. They adapt to frequent switching, bidirectional charge-discharge and fluctuating operating conditions, improving energy conversion efficiency, reducing equipment size and extending service life. They are also applicable to high-power UPS, SVG, APF and medium-frequency induction heating power supplies, stabilizing operation and enhancing power density.

Moreover, they support rail transit traction converters, new energy commercial vehicles and construction machinery electronic control systems, with excellent adaptability to complex temperature and load fluctuations. They also cover welding power supplies, high-voltage OBC on-board chargers, as well as marine and mining explosion-proof converters with strict EMI and reliability requirements.

This series of diodes are not recommended for low-frequency operating conditions below 1kHz, where their superior performance cannot be fully utilized. For pure power-frequency rectification scenarios without freewheeling demands, conventional rectifier diodes are more cost-effective.
