Diodes - Zener - Single

Diodes - Zener - Single

A 2EZ180D2E3/TR12 is a type of single zener diode. It uses a reverse-biased junction to produce a voltage stabilizing effect for a range of circuit applications. This type of diode is incredibly versatile and can be deployed in a wide range of trades and industries.

What is a Zener Diode?

At a basic level, a Zener diode is a type of diode that allows a reverse current to flow under the application of what is known as a Zener voltage. It is this voltage that causes the diode to behave differently to a standard diode, allowing the passage of a current in the reverse direction.

What is the Working Principle of a Zener Diode?

The working principle of a Zener diode is to provide regulated voltage control. In its simplest form, a Zener diode is a reverse- biased junction. When a positive voltage is applied across the diode, it behaves as a regular diode and prevents current from passing. However, if the voltage is reversed and increased, it can cause a breakdown of the junction and a current to flow in the reverse direction. The level of the Zener voltage at which this occurs is determined by the diode and called the Zener voltage.

The Uses of a Zener Diode

Zener diodes can be used for a wide range of circuit applications, particularly in power supplies where it keeps the voltage across the load within a certain range. They also have other uses such as providing a voltage reference in frequency to voltage converters, protecting circuits from overvoltage and even in semiconductor device characterization.

The 2EZ180D2E3/TR12 Zener Diode

The 2EZ180D2E3/TR12 is a single zener diode with an average dynamic resistance of 4.5 Ω at a nominal 1 mA current flow, and a Zener voltage that ranges from 15 to 30 V, with a usable reverse voltage range of up to 60 V. It\'s able to handle up to 1 W at a maximum ambient temperature of 125°C and its dimensions are particularly small with a length of 0.32 in (8.3 mm) and a width of 0.2 in (5.2 mm).

Conclusion

The 2EZ180D2E3/TR12 is an incredibly useful single zener diode that can handle a wide range of voltage ranges and applications and is particularly suitable for small electronics. Its ability to provide voltage regulating, reference, protection and even device characterization makes it an invaluable piece of equipment for many trades and industries.
