Diodes, in general, are devices which restrict the flow of electricity in only one direction. Zener diodes are special types of diodes which are specifically designed for function in breakdown mode and allow the flow current in either direction when the breakdown voltage is surpassed. 2EZ47D2/TR12 is one instance of a single Zener diode.

2EZ47D2/TR12 Application Field

The primary application field of the 2EZ47D2/TR12 single Zener diode is in the widely known and employed Zener Voltage Regulators Circuit. This component enables the steady output of a specific voltage and is the go-to component for many applications where voltage stabilization is required. For example, it can be used in oscillators and other circuits where constant voltage is necessary, as well as in smoothing circuits to provide a solid voltage reference. Furthermore, these types of devices can be employed to protect other components that may be sensitive to overvoltage by serving as a shutdown component and cutting off the electric current when needed.

2EZ47D2/TR12 Working Principle

The key principle behind the functioning of Zener diodes and, in this case, 2EZ47D2/TR12, is an intentionally created breakdown voltage effected by doping a junction area in the diode. This doping has the result of thermodynamically increasing the electric field strength at the junction area, which then causes the breakdown to occur when the specified voltage is exceeded. When the specified voltage point is surpassed, the diode allows then current to flow, when both anode and cathode are simultaneously connected to a positive potential, this results in the two connections being at the same potential and thus, no current will flow.

The breakdown voltage that the specific Zener diode is predetermined to allow is exhibited by its zener characteristic, which is measured and shown on the specific Zener diode’s data sheet. In terms of 2EZ47D2/TR12, this breakdown voltage is stated to be 4.7 volts.

Conclusion

To conclude, the 2EZ47D2/TR12 single Zener diode is an invaluable semiconductor device as it provides consistent and reliable voltage stabilization. The 2EZ47D2/TR12 offers a current capacity of 500 mA and exhibits a voltage rating of 4.7 volts. Its primary application field is within the Zener Voltage Regulators Circuit where it has the purpose of providing a strong, steady voltage reference. In addition, it is used in many other applications where voltage stabilization is necessary, as well as to protect other components from overvoltage.
