2. High current capacity

3. High surge current resistance

4. Low forward voltage drop

5. Low reverse leakage current

Application of Ultra Fast Recovery Diodes:

With the development of power electronics technology towards high-frequency and modularization, FRED, as a high-frequency device, has also flourished and is now widely used in various high-frequency inverter devices and chopper speed control devices. It plays a role in high-frequency rectification, continuation, absorption, isolation, and clamping, which is beneficial for the development of high-frequency inverter welding machines, high-frequency switch type electroplating power supplies, high-frequency high-efficiency switching power supplies, high-frequency fast charging power supplies in China High frequency frequency conversion devices and power factor correction devices will play a driving role.

These high-efficiency, energy-saving, energy-saving, and material saving high-frequency inverter devices, which can improve product quality and labor productivity, will gradually replace the thyristor power supply that is currently being mass-produced, bulky, inefficient, and severely polluting the power grid. They will play a decisive role in accelerating the update cycle of China's power electronic products.
