MAZ80820ML Application Field and Working Principle

Introduction to Diodes - Zener - Single

Diodes - Zener - Single is a type of diode used to regulate voltage. It is mainly used in DC power supply circuits. When a steady voltage is applied to the diode, the voltage will remain constant and the current will remain undisturbed by any external factors. It is an ideal device to be used in the fields of signal sensors, signal buffers, power supply systems, EMI filtering, radio frequency interference and other voltage regulation applications.

MAZ80820ML Application Field and Working Principle

MAZ80820ML is a silicon Zener diode designed to provide a stable voltage reference with a wide range of current. It is specifically designed to protect device that are powered using a DC power supply from noise, over-voltage, polarity reversal, etc. MAZ80820ML has the characteristic low voltage drop (VF = 1.4 V) and high power rating (Power Dissipation = 1.8 Watts). The diode also has excellent noise immunity and offers high temperature stability. The working principle of MAZ80820ML is as follows. When a reverse voltage is applied to the diode, the voltage increases with an exponential increase in the current. However, when the applied voltage reaches the “knee” voltage of the diode, a sharp increase in the current is experienced. This sudden spike in the current is referred to as “avalanche breakdown”. When this breakdown occurs, the diode fast enters into its active region, which is characterized by a constant voltage and very low current. The MAZ80820ML diode offers a very stable voltage for a wide range of current. This makes the diode ideal for protecting against power supply noise, over-voltage and other problems.

Conclusion

MAZ80820ML is a Zener diode designed to provide a stable voltage reference with a wide range of current. It is ideally suited for applications requiring high temperature stability and noise immunity. Its working principle is that when a reverse voltage is applied to the diode, the voltage increases with an exponential increase in the current, and when the applied voltage reaches the “knee” voltage of the diode, the diode enters a stabel active region with a constant voltage and a very low current. MAZ80820ML is an ideal device to be used in the fields of signal sensors, signal buffers, power supply systems, EMI filtering, radio frequency interference and other voltage regulation applications.
