The low forward voltage drop of Schottky diodes is a big advantage. In electronic circuits, reducing the forward voltage drop can reduce the conduction loss and improve the system efficiency. However, while further reducing the forward voltage drop, the reverse leakage current may increase, which will have a negative impact on the performance of the system. Therefore, optimizing the forward voltage drop requires finding a balance between conduction loss and reverse leakage current.
Methods:
Material selection optimization: The use of different semiconductor materials can significantly affect the forward voltage drop of the Schottky diode. Silicon (Si)-based Schottky diodes usually have a forward voltage drop of 0.15V to 0.45V, while wide bandgap materials such as silicon carbide (SiC) and gallium nitride (GaN) can maintain a low forward voltage drop while reducing leakage current, which is particularly suitable for high-frequency and high-temperature applications.
Package technology optimization: The use of advanced packaging technology, such as chip packaging (SMD) or optimized bare chip packaging, helps reduce the parasitic resistance in the package, thereby reducing the overall voltage drop.
