In a zener diode with high breakdown voltage
WebFinally, the power diode losses - both on-state losses and switching losses - are examined in a convertor circuit, including a comparison of silicon p-n diodes and 4H-SiC Schottky diodes. Learning objectives: • Provide students with a detailed understanding of High-Voltage Schottky and p-n diodes. • Students will be able to calculate key ... WebSince diodes with high breakdown voltage are lightly doped, they form a wide depletion layer (forbidden band). Conversely, since diodes with low breakdown voltage are heavily doped, they form a thin depletion layer (forbidden band). When a diode has a wide depletion layer, electron tunneling (Zener breakdown) is less likely to occur, causing ...
