Definition and characteristics of Fast Recovery Diode

Fast Recovery Diode is a diode mainly used in power conversion circuits. It is characterized by a low forward conduction voltage drop during forward conduction and a high reverse withstand voltage during reverse blocking. The primary function of this diode is to return to the initial state quickly and have a short recovery time, which meets the needs of power systems for high-frequency and high-temperature applications.

Compared with conventional diodes, the Fast Recovery Diode has a shorter recovery time, usually at the microsecond level, and its reverse withstand voltage is also higher, which can reach hundreds or even thousands of volts. In addition, the Fast Recovery Diode has a low forward voltage drop, which can reduce the energy consumption of the rectifier circuit and improve efficiency. Therefore, the Fast Recovery Diode is widely used in high-frequency, high-efficiency electronic equipment, such as switching power supplies, inverters, UPS, etc.

Things to note when using Fast Recovery Diode

  1. Select the appropriate model and specification of the Fast Recovery Diode according to the application scenario to ensure it can operate stably under normal working conditions.
  2. Correct connection method: Fast Recovery Diode has one-way conductivity, so you need to pay attention to the connection method to ensure the correct current direction. At the same time, avoid connection errors that may cause device damage or performance degradation.
  3. Consider the influence of temperature: The performance of the Fast Recovery Diode is greatly affected by temperature, so when using it, you need to pay attention to controlling the temperature of its working environment to avoid overheating or overcooling.
  4. Pay attention to the safe working area: The working status of the Fast Recovery Diode is limited by the safe working area. Exceeding the safe working area may cause device damage or performance degradation. Therefore, you need to pay attention to controlling the operating current and voltage within the safe working area when using it.
  5. Choose a suitable heat dissipation solution: Since the Fast Recovery Diode will generate a certain amount of heat when working, it is necessary to choose a suitable heat dissipation solution, such as heat sinks, air cooling, etc., to reduce the operating temperature of the device and improve its reliability and stability.

Fast Recovery Diode vs. Conventional Diode

  1. Short recovery time: The recovery time of a Fast Recovery Diode is usually at the microsecond level, while the recovery time of conventional diodes is usually at the millisecond level. This enables Fast Recovery Diode to adapt to high-frequency or fast-changing application requirements.
  2. High reverse withstand voltage: The Fast Recovery Diode has a high reverse withstand voltage, which can reach hundreds or even thousands of volts, while the reverse withstand voltage of conventional diodes is usually lower. This enables Fast Recovery Diode to adapt to high voltage or power application requirements.
  3. Low forward voltage drop: The Fast Recovery Diode has a low forward voltage drop, which can reduce the energy consumption of the rectifier circuit and improve efficiency. This is an essential feature of Fast Recovery Diode, giving it an energy-saving and efficiency advantage.
  4. Suitable for high-frequency conversion circuits: Because the Fast Recovery Diode has fast recovery capabilities and high voltage resistance, it is suitable for high-frequency conversion circuits. This makes the Fast Recovery Diode widely used in switching power supplies, inverters and other fields.
