The SK20H45 B0G is an electronic rectifier manufactured by ROHM. It has a wide range of applications in various electronic and industrial devices, including AC adapters, power supplies, LED lighting, electric vehicles, and more. In this article, we will discuss the application field and working principle of the SK20H45 B0G.

Application Field of SK20H45 B0G

The SK20H45 B0G is a single-phase bridge rectifier with a high voltage rating of 200V and a total peak forward surge current of 13A. It has a 6A RMS current carrying capability and a package size of 20mmX45mm, making it ideal for space-saving applications. It is suitable for applications where large current is required, including AC to DC conversion, medical equipment, battery chargers, and more. It is also ideal for power supplies, DC power converters, and other common uses.

The SK20H45 B0G has a high surge capability and a low reverse recovery time making it well-suited for demanding applications such as electronic monitoring systems. Its low junction capacitance ensures good noise immunity, making it suitable for use in noisy environments like computer monitors and servers. It also comes with a variety of features such as a simplified EMI filter, built-in protection diodes, and an LED indicator.

Working Principle of SK20H45 B0G

The SK20H45 B0G works similarly to other two- and four-terminal diode bridges. It can be thought of as having two sets of power inputs and two sets of power outputs. The device is a full-wave rectifier, meaning it converts AC power into DC in two distinct steps. In the first step, each of the two power inputs is connected in turn to one of the power outputs, generating a current pulse in the process. In the second step, the reverse connection is made, causing the current to flow back onto the input side.

The SK20H45 B0G acts as a switch and regulates the flow of current, preventing too much current from flowing at once. This makes it an efficient and reliable source of power, even in high-load applications. In addition, the SK20H45 B0G has an integrated reinforced isolation structure, ensuring it can withstand even the most extreme temperature and humidity conditions.

The SK20H45 B0G is also equipped with a wide device operating temperature range and a robust EMI filter, meaning it can be used in a variety of applications. The wide operating temperature range ensures long life and reliable performance, while the EMI filter provides superior EMI/EMC performance, making it suitable for sensitive applications.

Final Thoughts

The SK20H45 B0G is a robust and reliable single-phase bridge rectifier with a range of features that make it ideal for many different applications. Its high voltage rating and low reverse recovery time make it suitable for high-demand applications, while its integrated reinforced isolation structure and wide operating temperature range ensure reliable operation even in extreme conditions. Its LED indicator, built-in protection diodes, and EMI filter make it a versatile and reliable rectifier for high-power applications.
