MUR490E

MUR490E is a fast-recovery diode commonly used in applications such as AC/DC adapters and battery chargers. It is a single-ended, unidirectional, high-current rectifier with a reverse polarity voltage rating of 400V. This diode is a fast-acting rectifier with a typical turn-on time of 3ns, while the reverse recovery time is 200ns.

MUR490E is a high power density diode with a low forward voltage drop, making it ideal for switching power supplies and other power conversion applications. It handles a large amount of current without generating excessive heat, and its low capacitance means it is ideal for high-frequency power communication. This diode also has a low reverse leakage current and low forward voltage, which makes it suitable for constant current applications.

The most common application of MUR490E is in bridge rectifier circuits. In these circuits, multiple diodes are used to connect an AC input signal to a single DC output. This application requires a diode that can handle a large number of cycles and still maintain a low forward voltage drop, making the MUR490E a perfect choice. This diode is also used in static switch circuits and other power control applications.

The working principle of the MUR490E is based on the PN junction concept. When a reverse biasing voltage is applied across the diode, the minority charge carriers are swept from the N-region to the P-region. This causes a potential barrier to be formed between the two regions, preventing further current flow. When a forward biasing voltage is applied across the diode, the majority (majority diffusion current) carriers are swept from the P-region to the N-region and a low-level junction current is established, causing the diode to conduct electricity.

The MUR490E is a high-powered, low forward voltage drop diode. It is commonly used in applications that require low capacitance and fast switching speeds. Its low reverse leakage current and low forward drop make it suitable for a variety of power control and AC/DC conversion applications. The diode also offers a high power density and a wide range of operating temperatures, making it a versatile and cost-effective rectifier solution.

MUR490E is a great choice for applications requiring low-power current control. It is perfect for use in bridge rectifier circuits, static switch circuits, and other power AC/DC conversion solutions. The diode is also a great option for high-frequency power communication due to its low capacitance and fast-switching capabilities. MUR490E is an affordable and reliable diode for various power control and AC/DC conversion needs.
