25CTQ045S

Diodes and rectifiers are an important part of many applications, from power supplies to amplifiers to radio receivers. Their versatility extends to rectifier arrays, which are used to manage and convert large amounts of current into a regulated voltage. 25CTQ045S is one such array, a Schottky diode rectifier array with a total forward voltage of just 0.9V, making it suitable for applications where low power and high efficiency are a priority. In this article, we’ll look at the 25CTQ045S application field and working principle.

The 25CTQ045S is a 45V Schottky rectifier that can handle up to 18A of current. It’s ideal for automotive, battery chargers, and home appliance applications, as well as general-purpose power supplies and lighting systems. It has a very low on-state resistance of just 0.045Ω and low forward voltage of 0.9V. This makes the 25CTQ045S an ideal choice for applications that require high efficiency, low switching loss and noise, and robustness.

As far as the working principle goes, the 25CTQ045S utilizes a traditional full-wave bridge rectifier design, allowing it to convert AC input to DC output with high efficiency. The rectifier array is composed of four Schottky diodes arranged in a bridge configuration. When the AC source is connected to the input terminals of the rectifier, the Schottky diodes conduct in tandem, allowing the current to flow through the load. During one half cycle of the output, the current flows through the positive side of the rectifier, while during the other half cycle, the current flows through the negative side. This arrangement ensures that the current is always flowing in the same direction, allowing for more efficient power conversion.

The 25CTQ045S is an excellent choice for many applications, due to its low losses, low forward voltage, and high efficiency. It also offers a high surge current rating, which makes it ideal for applications that require high current power conversion. Its low on-state resistance makes it well-suited for high-frequency switching applications, and its compact size allows for easier installation and improved reliability. All in all, the 25CTQ045S is an excellent choice for both low power and high current applications.
