The B0530W SOD-123 Schottky Barrier Diode (SBD), manufactured by Bourne, is a diode used to control current flow in a circuit. It has a peak forward voltage drop of 430mV at 500mA, an operating current of 130µA at 30V, and is RoHS compliant. The diode is small in size and can be easily mounted within the circuit board. It can be used in consumer applications such as LED drivers, audio amplifiers, power supplies, electronic switches, etc. It also has a high power efficiency and low power dissipation allowing it to sustain high power wattage in relatively low temperatures.
