A higher reverse breakdown voltage ensures better performance in high-voltage applications. 3. Thermal Conductivity: High power diodes generate heat during operation. Good thermal conductivity helps dissipate heat, ensuring the diode operates within its specified temperature range. 4. Switching Speed: The switching speed of a diode is the time it takes to switch from the off-state to the on-state and vice versa. A faster switching speed results in higher efficiency and lower power loss. 5. Reliability: The reliability of a high power diode is crucial for ensuring the stability and longevity of electronic devices. Factors such as material quality, manufacturing process, and environmental conditions can affect the reliability of diodes.
