R5100410XXWA is a single rectifier diode packaged in a 1.0mm x 0.5mm UDFN, a miniature surface-mount package. The diode has a low power dissipation and a small junction capacitance, making it well suited for high-frequency switching.

Applications

R5100410XXWA rectifiers can be used in various low-power switching applications, such as mobile phones, automotive electronics, computing, and consumer electronics. It is also suitable for use in other low-power applications such as medical devices, handhelds, and rechargeable batteries.

Due to its ultra-low forward voltage drop (as low as 0.2 V at 5 mA) and low power consumption, it can be used in DC-DC converters, including buck, boost, and flyback converters, as well as in AC-DC switching power supplies. The low power dissipation and junction capacitance also make this rectifier suitable for a variety of high-frequency data communication applications, including those used in USB 3.0, HDMI, and Ethernet.

Working Principle

Rectifier diodes are two-terminal devices that allow the flow of current in one direction only. A single rectifier is composed of a P-N junction, and works by rectifying an input AC voltage to a DC output voltage. When a voltage of sufficient magnitude forward-biases the junction, current flows through the diode, and it remains in a forward-biased state until the voltage falls below a certain threshold.

R5100410XXWA single rectifier is a four-layer diode that employs a hyperfast recovery time. This helps reduce the output voltage ripple reduces switching losses and requires less stabilization capacitance. It also helps to reduce interference and EMI, and eliminate the need for extra filtering.

The 1.0mm x 0.5mm UDFN package used for this rectifier helps to reduce the size of the assembly and offers increased resistance to mechanical stress. Additionally, the package offers superior thermal and electrical performance, and improved RF shielding, compared to conventional packages.
