Diodes - Rectifiers - Arrays concepts are essential for understanding the application and working principle of the BAS40DW-05-7. The BAS40DW-05-7 is an epitaxial over-voltage protected small signal Diode Array comprised of four Schottky diodes and four Diode Bridges with individual protection circuits. This Diode Array is particularly suitable for LCD backlight applications.A diode is a device that consists of two pins, the anode and cathode, and is made up of a semiconductor material. It allows the flow of electric current in only one direction, and when used in Arrays, it helps protect circuits against voltage spikes.Schottky diodes are commonly used in high-frequency circuits, where their tolerance for high speeds is essential to avoid loss in signal integrity. They use metal-semiconductor junctions, which enable them to switch faster than PN junction diodes, and at considerably lower voltages. Due to their low forward voltage drop and reverse leakage current, they are also commonly used in absolute maximum protection systems.A diode bridge, or bridge rectifier as they are sometimes called, is a device that contains four separate diodes, arranged in a "bridge" configuration and are mainly used for AC to DC conversion. In other words, it converts alternating current (AC) to direct current (DC). In the case of the BAS40DW-05-7, the four Schottky diodes and four Diode Bridges protect the circuits from any over-voltage surges.Individual protection circuits are one of the most important features of the BAS40DW-05-7 as they provide extra reliability in terms of voltage protection. With the protection circuits, any excessive current or voltage will not be able to damage the LCD backlight, thus preventing any malfunctions.The BAS40DW-05-7, as a Diode Array, can effectively protect the circuits from any over-voltage surge. Its four Schottky diodes, four Diode Bridges and individual protection circuits ensure the reliability and safety of the LCD backlight and other circuits. The feature of over-voltage protection also makes it a suitable choice for LCD backlight applications.
