The B5819W with Schottky Barrier Diodes (SBD) in SOD-123 case is a RoHS compliant diode manufactured by Jingdao. This diode has a low forward voltage drop, and can handle high surge current. It is suitable for rectifying very high frequency, low impedance AC power supply circuits, and especially for switching power supplies. It features low thermal resistance, fast switching action, and low power losses. Its small SOD-123 package and low profile save PCB space and component height. It also has great environmental performance, with excellent ESD protection and high temperature stability. This diode is manufactured to stringent testing and quality and performance standards and is suitable for SMD applications.
