Introduction to Zener Diodes
Neso Academy・10 minutes read
Xena diodes are utilized for voltage regulation in various loads, with Avalanche breakdown in lightly doped diodes and Zener breakdown in highly doped Xena diodes explained. These diodes possess high power dissipation capabilities and can function in breakdown regions without degradation, offering versatility in forward bias conditions as well.
Insights
- Xena diodes are versatile components that can function both as voltage regulators in reverse bias and as regular diodes in forward bias, showcasing their adaptability in various circuit applications.
- The breakdown mechanisms in Xena diodes differ based on doping levels: Avalanche breakdown in lightly doped diodes involves electron energy gain, while Zener breakdown in highly doped diodes occurs due to covalent bond rupture from a strong electric field, highlighting the nuanced physics behind their operation.
