Diodes are a type of energy conversion device that converts AC energy into DC energy and can be used to stabilize the current. Rectifier diodes, also known as rectifier diodes, are also a type of diode that can be used to convert alternating current (AC) into direct current (DC) for rectification, and are commonly used in applications such as power supply, rectification, and voltage stabilization. The BAT54W-HE3-18 is an integrated, high-efficiency rectifier with low forward voltage drop and tight reverse leakage current; it is suitable for desktop computer power supplies, TV sets, and other types of switching power supplies. This article will explain the application field and working principle of the BAT54W-HE3-18.

Applications of the BAT54W-HE3-18

BAT54W-HE3-18 is mainly used in computer desktop power supply systems. Desktop computers use AC power supply, but the computer’s internal circuit needs to use direct current, so rectification is required. The neccessity of rectification is due to its inherent stability, making it more suitable for use in electronic circuits. In addition, it can also be used in other electronic switching power supplies, such as home televisions, televisions, and other electronic products.

BAT54W-HE3-18 Working Principle

Every diode consists of a PN junction, which is a boundary between the material containing excess positive charges (the "P-type" material) and the material containing excess negative charges (the "N-type" material). When a voltage is applied to it, the built-in electric field forces the mobile positive and negative charges to move to the P and N sides respectively, establishing a rectifying connection of the diode.The plate of the diode is usually composed of one or more N-type semiconductor materials and one P-type semiconductor material. Connected to AC input leads, the anode (A) is wired to one side of the AC power, and the cathode (K) is wired to the other side of the AC power.

Under the action of the applied voltage, electrons flow from the negative pole to the P layer, forming a PN junction, that is, a rectifying diode. In the forward biasing direction, the current is mainly composed of electrons; in the reverse biasing direction, the current is mainly composed of holes, and the current is much smaller than the forward current. When a high voltage is applied in the forward direction, high current can flow through the diode and it will be in the ON state. When the voltage is reversed, the diode is in the OFF state.

The BAT54W-HE3-18 is an integrated, high-efficiency rectifier diode. It has a good overall performance, low forward voltage drop, fast switching speed and low reverse leakage current, suitable for power supply and voltage stabilization. It can meet the requirements of various switching power supplies, because of its features such as high efficiency and good heat dissipation, which can make the switching power supply better in terms of temperature performance and heat dissipation.
