SDUR1520 Application Field and Working Principle

The SDUR1520 is a single rectifier diode designed for general rectification of power supplies up to 15A. Typical applications include air conditioning, communications, industrial automation, medical device and automotive industries.

The SDUR1520 utilizes an advanced high-power design capable of passing high currents and providing outstanding surge current capability. It also provides low reverse voltage drop, low forward voltage drop and superior reverse current leakage.

Features

• Forward Current Ratings: 0.7A to 15A
• Reverse Voltage Ratings: 10 to 1800V
• Surge Current: 250A (2ms half-sine)
• Low Forward Voltage Drop
• Low Reverse Voltage Drop
• High Saturation Voltage
• High Voltage Rating

Working Principle

In order to understand the working principle of the SDUR1520, it is important to first understand the basic components of a rectifier. There are two main components of a rectifier circuit, the diode and the transformer. The diode converts AC power into DC power and the transformer steps down the voltage to match the desired voltage requirements of your application.

The SDUR1520 consists of two parts, an anode and a cathode. When a positive voltage is applied to the anode and a negative voltage is applied to the cathode, current will flow in the forward direction. This is known as forward biased and is the desired action of the device. This allows current to flow in one direction only, which is needed to convert AC power into DC power. If the opposite polarity is applied, current will not flow and the diode is said to be reverse biased. This prevents current from flowing in the opposite direction and is used to protect the components from high voltages.

The SDUR1520 is capable of withstanding high current and voltage levels due to its high voltage and low voltage breakdown ratings. This allows it to be used in applications such as air conditioning, industrial automation, medical device and automotive industries, where high currents and voltages are involved. The SDUR1520 also has a low forward voltage drop and a high surge current allowing it to handle high transient loads.

Conclusion

The SDUR1520 is a single rectifier diode designed for general rectification of power supplies up to 15A. Its features include low forward and reverse voltage drops, high saturation voltage, high voltage ratings and high surge current ratings. Its working principle consists of two main parts, the anode and the cathode, which upon the application of the correct polarity, allow current to flow in one direction only, hence converting AC power into DC power. The SDUR1520 is designed to withstand high currents and voltages, making it suitable for air conditioning, industrial automation, medical device and automotive industries.
