The SD103AX SOD-523 Schottky Barrier Diode (SBD) ROHS manufactured by FUXINSEMI is a diode used in electronic circuits. This diode has a low voltage and current rating, making it ideal for protecting sensitive electronic components and systems from voltage and current spikes. It features a low forward voltage and fast switching time, which makes it suitable for a wide range of applications such as motor controllers, computer peripherals, power supplies, and voltage references. Additionally, this diode uses a Schottky barrier structure for relatively low forward voltage drop, allowing for efficient power dissipation compared to regular diodes. The diode also meets Industry standard RoHS standards for hazardous substances, ensuring that it is safe and reliable for use in devices and products. It is available in bulk quantities, making it an economical choice for circuit designs.
