Introduction

MMSZ4680ET1 is an ultra-low VF, forward voltage temperature stabilized, axial leaded power Zener diode. This diode is used for the regulation of voltage from 5.2 to 6.5 Volts at 4-500mA. It consists of an avalanche breakdown mechanism which can provide shunt path for current. This provides regulated voltage and increases efficiency, reducing voltage drop over the component and allowing for stable power delivery to the load. This component is suitable for a variety of applications and can be selected for different functions depending on the application.

Application Field

MMSZ4680ET1 is suitable for a variety of applications including power supply, battery protection, telecommunications and other devices which require high reliable voltage regulation. With low forward voltage, temperature stability, high current capacity and high voltage breakdown protection, it provides a complete solution for many applications. It is widely used in regulated power supply applications where voltage regulation is desired. The ability to effectively regulate voltage output ensures smooth power delivery to the load resulting in reliable performance. It is used in mobile phone batteries and other portable devices.

Working Principle

The MMSZ4680ET1 works on the PN junction principle which creates a barrier to the movement of electric current. When the voltage across the device is greater than the minimum breakdown voltage, a high-current RC circuit is formed and the voltage across the device decreases. At this point, the PN junction acts as a diode and the diode junction comes in direct contact with the electric current. This is known as forward voltage drop, which is very low in MMSZ4680ET1. This low voltage drop allows for better regulation of the power supplied.The device also has a temperature stability characteristic which ensures it maintains a stable output voltage even when the temperature of the ambient environment changes. This ensures reliability and stability in multiple applications.

Advantages

The MMSZ4680ET1 has several advantages. It has low forward voltage drop, high-current capacity, and temperature stability; all of which make it suitable for a wide variety of applications. Additionally, it is ideal for regulated power supply applications. The low forward voltage drop ensures stable power delivery to the load and the temperature stability ensures that the voltage output remains consistent even with changes in temperature.

Conclusion

MMSZ4680ET1 is a low-voltage, temperature-stabilized, axial leaded power Zener diode. It offers low forward voltage and temperature stability, and high-current capacity allowing it to be used in a wide variety of applications. It is suitable for power supplies, battery protection, telecommunications and other voltage regulation applications. The low forward voltage drop ensures stable power delivery and the temperature stability ensures that voltage output remains consistent. This makes MMSZ4680ET1 an ideal component for reliable, high performance applications.
