Working Principle

The 1EZ130D5E3/TR8 Zener diode works on the principle of a voltage-variable resistor. When a reverse voltage is applied to the diode, an electric field is created between the anode and the cathode. This field will cause a current, which will increase as the applied voltage increases. The Zener breakdown voltage of the 1EZ130D5E3/TR8 is around 5.3V.

Above the breakdown voltage, the diode will act like a normal diode with a very high electric resistance and will only allow a small amount of current to flow. Below breakdown voltage, the reverse leakage current in the diode increases exponentially and is used as a source of precise voltage regulation.

The Zener diode also exhibits a characteristic thing called Zener impedance. This is the resistance that the diode exerts when the voltage across it is equal to the Zener voltage. At this point, the Zener diode will act like an open-circuit and the current flowing through it will be very small.

Conclusion

The 1EZ130D5E3/TR8 is a versatile and reliable low-power Zener diode that can be used for a wide variety of applications where precise voltage regulation is needed. Its low reverse leakage, high purity, and low dynamic resistance make it ideal for use in voltage regulation, latching, and clipping circuits. It is also a great choice for automotive applications, providing over-voltage protection and improved power supply performance.
