The RB551V-30 is a Schottky barrier diode (SBD), meaning it allows current to flow in one direction only, thus preventing any reverse flow and protecting other components in the circuit. It is manufactured by Pingjingsemi and is RoHS compliant. The RB551V-30 is a 30V 470mV@500mA 500mA SOD-323 package containing two Schottky Diodes, which are commonly used for fast switching applications in telecommunications and other sensitive applications due to their low forward voltage drop. The low voltage drop of SBDs makes them suitable for use in battery-operated equipment, allowing for the most efficient use of the available power. The RB551V-30 is also available in other package sizes, including SOD-123, SOD-523, TO-92, and TO-73.
