Unlike traditional diodes, high-power diodes are specifically engineered to operate at high power levels, offering improved performance and efficiency.

Principles of Diode High Power

The working principle of a diode high power is based on the P-N junction, which allows current to flow in one direction while blocking it in the opposite direction. High-power diodes are typically made of silicon carbide (SiC) or gallium nitride (GaN) due to their excellent electrical properties, such as high breakdown voltage, low forward voltage drop, and fast switching speed. The P-N junction in a high-power diode is designed to handle high current and voltage levels. This is achieved by increasing the doping concentration, which reduces the resistance of the junction and allows more current to flow. Additionally, the diode's physical structure is optimized to dissipate heat effectively, ensuring reliable operation at high power levels.
