Diodes - Zener - Single - 3EZ14D5/TR12 Application Field and Working Principle

Diodes - Zener - Single - 3EZ14D5/TR12 is a designed specifically for voltage regulation and breakdown control applications. 3EZ14D5/TR12 diodes comprise a series of 9V single Zener diodes, with a single breakdown level of 9V and wattages ranging from 500mW-1W. The internal construction of a 3EZ14D5/TR12 diode is a combination of a die-like PN junction diode, a Zener diode, and a reverse-breakdown diode.

The term Zener diode is derived from the fact that the device remains in a non-conducting state until a specific breakdown voltage is reached. Beyond this, the “Zener voltage” is maintained with any further increase in voltage.

Applications of 3EZ14D5/TR12

3EZ14D5/TR12 diodes are most commonly used in situations where the need for precise voltage regulation and breakdown control is vital, such as in power supplies, DC amplifiers, and audio/visual equipment.

It is also commonly used as a reference source in a variety of industrial systems, such as in transducer sets and other sensing applications. 3EZ14D5/TR12 diodes are often included in various product designs to perform different functions are small radio receivers, astable multivibrators, and timers.

Working Principle of 3EZ14D5/TR12

At low reverse voltages, the 3EZ14D5/TR12 acts as a PN junction rectifier/diode, allowing current to flow in only one direction. When the reverse voltage exceeds a certain break-down voltage, however, the diode suddenly changes its state, allowing current to flow in both directions.

This phenomenon, known as "breakdown voltage regulation," is at the heart of the 3EZ14D5/TR12\'s operation. When the reverse voltage exceeds the breakdown voltage, the voltage across the diode maintains itself at a relatively constant level, regardless of further increases in voltage.

The voltage remains at the same level until enough current is passed through the diode to damage it. During this process, the breakdown voltage of the diode adjusts itself according to the load on the circuit, resulting in a highly reliable voltage regulation.

The 3EZ14D5/TR12\'s performance has been optimized for low reverse current drop and resistor-like behavior in terms of linearity and low-temperature coefficient. It also offers low power dissipation and fast switching speeds.

Conclusion

In summary, 3EZ14D5/TR12 diodes are small, versatile devices that have excellent voltage regulation properties and can be used in a variety of applications. The fact that they are constructed from a combination of a PN junction diode, a Zener diode, and a reverse-breakdown diode makes them reliable and robust, and their ability to maintain close control over the breakdown voltage makes them ideal for applications that require precise voltage regulation and breakdown control.
