The RB521S-30-MS SOD-523 Schottky Barrier Diode (SBD) with 30uA@10V 30V single 500mV@200mA 200mA and ROHS manufactured by MSKSEMI is a type of diode that is specifically used in applications that require high-voltage switching, such as automotive electronics or high-current switching applications. It is a robust and reliable device that is composed of an SBD substrate, P-type metal, N-type metal, and an encapsulation. The main benefit of SBDs is that they offer fast switching speeds, low On-State resistance, and high breakdown voltage. The RB521S-30-MS is capable of withstanding a maximum reverse voltage of 30V and can provide a current carrying capability of up to 200mA. Finally, as it is RoHS compliant, it is suitable for use in all green electronics applications.
