The MUR480EG diode is a single, high-efficiency rectifier commonly seen in power-supply, solar, and automotive applications. It is an ultra-fast, soft-recovery rectifier, with a maximum current capability of 48 Amps and a maximum repetitive peak reverse voltage of 800 Volts. This rectifier is highly reliable, operating mostly in a generator, starter, or alternator in automotive applications and featuring a low forward voltage drop and lesser power dissipation, which makes it suitable for many rectifier applications. The MUR480EG diode is most commonly used in applications that require a low forward voltage drop, high-power dissipation, quick recovery time, and high peak current capabilities for a given voltage rating.

The working principle of the MUR480EG single rectifier is quite simple. It is a four-layer device, with two p-n junctions, one electrically connected to the other. When a reverse voltage is applied, the p-n junctions become forward biased, allowing current to flow in the forward direction. The amount of current that flows through the rectifier is determined by the amount of voltage applied to the p-n junctions and the size of the rectifier package. The larger the package size, the more current it is able to handle.

In order to ensure the highest level of safety and efficiency, the rectifier should be mounted securely, using insulated bolts and washers, to avoid any short circuit or arcing. The two leads of the rectifier should be connected properly, with the anode lead to the positive voltage and the cathode to the negative voltage. Once the rectifier is properly wired, the current that passes through the device is rated in Amps, with the peak reverse voltage limited by the rated voltage of the rectifier.

In applications such as power-supply, solar, and automotive installation, the MUR480EG single rectifier provides good surge and overload protection, a low forward voltage drop, and soft-recovery period, allowing it to safely handle high currents. The high peak-current capability of this device makes it suitable for applications with high inrush current, such as starter or generator applications and applications that require rapid on-off switching operations. Additionally, the superior-temperature performance and high current ratings ensure that the rectifier is able to withstand frequent thermal stress and circuit overloads.

The MUR480EG single rectifier is a highly reliable, high-power device that is well-suited for a variety of rectifier applications. It is designed for high current handling capabilities and is able to operate in a temperature range of -55°C to +175°C. This rectifier also offers a low forward voltage drop and superior temperature performance, making it suitable for power supplies, solar, and automotive applications.
