Introduction

CMR3-02 BK is a product from the rectifiers and diodes collection. They are built from silicon-based semiconductor materials, and thus have good temperature characteristics. The rectifiers are most popularly applied in switch mode power systems as well as DC-AC and AC-DC converters.

Application Field

CMR3-02 BK rectifiers are mainly used in a variety ofswitch mode power supply (SMPS) systems such as those used in printers and computers. These rectifiers are also used in DC power supplies and AC-DC DC-AC and motor controllers. In addition, they are used in other switching and linear applications requiring low conduction and high voltage capabilities.

Working Principle

The CMR3-02 BK rectifier operates on the same basic principle as most other rectifiers. When a voltage is applied to its anode and cathode, it will allow current to transition from the anode to the cathode. It works on a simple on/off principle, allowing current to pass only when the applied voltage is greater than the barrier voltage of the rectifier. The rectifier has two main parameters: the forward drop voltage (Vf) and the reverse breakdown voltage (Vbr). The forward drop voltage is the voltage across the rectifier when the current is flowing in the forward direction. As a result, the forward drop voltage is always lower than the reverse breakdown voltage. The reverse breakdown voltage is the voltage required to cause current to flow in the opposite direction. This value is typically higher than the forward drop voltage. The reverse leakage current is the current that flows through the rectifier when it is in the off-state. This is an important parameter to consider as excessive leakage current can cause significant power losses.

Advantages

The CMR3-02 BK rectifier has several advantages. Firstly, it has a low forward drop voltage that allows it to operate efficiently at higher currents. Secondly, it has a high voltage breakdown rating, meaning it can handle high input voltages. Thirdly, its reverse leakage current is low, meaning it has low power losses in the off-state. Fourthly, it features a low capacitance rating, meaning it exhibits very low switching losses. Finally, its built-in temperature protection ensures that it does not become damaged in high temperature applications.

Conclusion

The CMR3-02 BK rectifier is a versatile rectifier that can be used in a wide range of applications. It features good temperature characteristics and an impressive forward drop voltage and breakdown voltage rating. Furthermore, its low reverse leakage current and built-in temperature protection makes it an ideal choice for high temperature applications. The CMR3-02 BK rectifier is thus a reliable and efficient choice for a variety of applications.
