Diodes play an important role in a wide array of electrical and electronic applications. Specifically, Zener diodes, a variation of standard diodes, are widely used to protect from voltage spikes or to offer a stable voltage as a reference. The 2EZ18D2/TR12 is one example of a single Zener diode. Its most common applications and working principle are discussed below.

Applications of the 2EZ18D2/TR12

The 2EZ18D2/TR12 is ideally suited for use in stabilizing the voltage supply to DC and logic circuits. It can also be used as an anti-noise filter or a voltage limiter. Additionally, it can be applied as a temperature compensator and rise time limiter. It can handle 1/2W of power, which makes it practical for use in a variety of small to medium-sized applications.

The versatile nature of the diode allows it to be used in DC to DC converters, LCD televisions and monitors, LCD backlight inverter circuits, computer and peripheral circuits, battery operated circuits, radio and audio equipment, and low voltage control boards, to name just a few applications.

Working Principle

As a Zener diode, the 2EZ18D2/TR12 is designed to provide stable and accurate voltage regulation at specified turns ratio. It has a Zener voltage of 18V and a Zener impedance of 2.2 ohms at 1W. The diode is designed to regulate voltage when the source voltage is higher than the diode’s breakdown voltage. The diode has a reverse breakdown voltage of 18V, and it conducts when the reverse bias voltage is up to 0.5V below the breakdown voltage.

When forward biased, the current flowing through the diode is proportional to the voltage drop, usually 0.7V. The Zener voltage remains constant, allowing the diode to maintain a steady and accurate output. When the current is greater than the diode’s rated current, the voltage regulator starts to increase and the diode’s Zener breakdown voltage loses its stability. The diode can handle up to 1W of power, beyond which the device should be shut down for safety.

Conclusion

The 2EZ18D2/TR12 is a single Zener diode that provides stable and accurate voltage regulation for a variety of applications. It can be used in DC to DC converters, LCD televisions and monitors, LCD backlight inverter circuits, computer and peripheral circuits, battery operated circuits, radio and audio equipment, and low voltage control boards. Its Zener voltage of 18V and Zener impedance of 2.2 ohms at 1W enable it to maintain a steady and accurate output, while its reverse breakdown voltage of 18V ensures that it is able to conduct current up to 0.5V below the breakdown voltage. The diode can handle up to 1W of power, beyond which the device should be shut down for safety.
