In this article we will explore the application field and working principle of the CDBM1100-HF diode, one of the most popular rectifier diodes used in various applications today.

Application Field

The CDBM1100-HF is predominantly used in applications with AC voltage rectification, such as photovoltaic installations, automotive electronics, wind turbines, building automation systems, etc. This diode is manufactured for use in both residential and commercial settings, and its high surge current ratings allow for strong rectification voltage, even under heavy-duty power input levels. This makes the CDBM1100-HF a perfect choice for applications where reliability and efficiency are paramount.

Working Principle

The CDBM1100-HF is a single rectifier diode made from silicon, and its structure consists of a cathode and anode, which are asymmetrically designed to permit maximum flow of electrons in one direction only. In general, diodes allow current to flow in one direction, while blocking it in the other due to their asymmetrical structure. When the anode of the diode is connected to the positive power source, current flows through the anode and onto the cathode. However, if the anode is connected to the negative power source, this flow is blocked, and the voltage across the diode is substantially reduced, thereby preventing damage to the semiconductors.

General Characteristics

The breakdown voltage of the CDBM1100-HF is between 400V to 600V, and it has three different peak levels - 1.44A, 2A, and 3A, ensuring it can cope with varying power loads. This diode has a low forward voltage and excellent surge capability, with a 20ms pulse current of up to 100A, a 500V high voltage, and a typical junction temperature of 125⁰C. In addition, the avalanche energy for this device reaches up to 4mJ, ensuring it can cope with extreme levels of power.

Conclusion

The CDBM1100-HF represents one of the best single rectifier diodes in terms of power efficiency and reliability, making them ideal for all sorts of applications. Their wide range of features, such as their high breakdown voltage, low forward voltage, excellent surge capability, and high avalanche energy, make them one of the best choices for AC voltage rectification. In conclusion, the CDBM1100-HF is one of the most sought after rectifier diodes available in the market today.
