Application Field

This diode is suitable for providing transient protection and voltage regulation in a variety of electronic applications. It is often used in charge pumps, voltage regulation circuits, power supplies and amplifier circuits. The diode can be used to guard sensitive integrated circuits from current or voltage overshoot or short circuits. It can also be used to facilitate switching between different power supplies or different voltage levels. In addition, the device can provide efficient energy management, allowing energy to be stored and released in a controlled manner, at the same time providing circuit protection.

Working Principle

EDZVFHT2R6.8B is a zener diode, which is a type of diode that is specifically designed to conduct specific amount of reverse current when the reverse voltage is greater than the pre-set zener breakdown voltage, thus limiting the maximum reverse voltage. When the forward voltage is less than the zener breakdown voltage, the diode operates in reverse conduction and the device acts as an ideal current source, thus providing a regulated output voltage. The diode also has a soft turn-on feature which allows the current to start increasing slowly with increase in voltage.

When the reverse voltage is greater than the breakdown voltage, the current starts to increase significantly and limits the maximum peak reverse voltage that can be applied across the device. This prevents the device from entering a destructive avalanche breakdown mode. At the same time, the current starts to increase exponentially, thus providing an additional level of protection and regulation. In addition, the diode has a reverse recovery time which helps in limiting the peak reverse current.

EDZVFHT2R6.8B has some distinct advantages over other zener diodes such as low inner resistance, large area of working temperature range, low power dissipation, high voltage stability and low cost.

Conclusion

In conclusion, EDZVFHT2R6.8B is a single zener diode specifically designed for easy implementation of voltage regulation and overvoltage protection in various applications. The diode offers low inner resistance, high voltage stability and low cost as compared to other zener diodes, and also has a soft turn-on feature and reverse recovery time that helps in limiting the peak reverse current and voltage.
