The RF051VA1STR is a single, high-efficiency rectifier diode from ROHM Semiconductor’s new family of low-profile power components. This device combines low forward voltage drop, low reverse leakage current, and high-speed switching in a miniature MFP surface-mount package for power management applications.

The RF051VA1STR is available in two version options. The maximum reverse voltage for the standard version is 50V and 100V for the high voltage version. The maximum forward current is 1A for both versions. This device features an extremely low reverse leakage current of 15nA (typ.), + 2µA (max.), which enables highly-efficient designs.

The RF051VA1STR is well-suited for a variety of applications, including AC/DC adapters, power supplies, computers, digital cameras, and other consumer electronics. The low-profile MFP surface-mount package saves board space and helps speed up assembly of compact electronic systems.

The working principle of the RF051VA1STR diode is based on the rectification process, which is the process of converting AC (alternating current) signals into DC (direct current) signals. It is achieved by using the physical property of a diode that only allows current to flow in one direction. When the diode is connected to a circuit with AC voltage, the i-v graph shows that only the positive half of the waveform reaches the load. The other half passes through the diode, but no current flows through the diode. This is called rectification, and it is the basis of the RF051VA1STR\'s working principle.

The RF051VA1STR single rectifier diode is designed to provide consistent, reliable performance in power management applications. Its low forward voltage drop and reverse leakage current, combined with high-speed switching, make it an ideal choice for applications where space and power saving are high priorities.
