3EZ75D5/TR12

Diodes - Zener - Single

The 3EZ75D5/TR12 is a type of a single Zener Diode. The design of a Zener diode is different from that of a traditional diode. As current is passed through the diode, a voltage that is proportional to the current is generated, which for Zener diodes is reversibly repeatable. This means the diode can both provide current and regulate current.

Application Field

The application of 3EZ75D5/TR12 can be found in various electronic circuits. It is often used to provide voltage references in regulating amplifiers and also works in power supplies that require voltage stabilization. The 3EZ75D5/TR12 is also used as a signal clamp in signal processing circuits in order to limit the levels of signal amplitude.

Working Principle

The operation of a Zener diode is based on the reverse breakdown voltage phenomenon. When a specific voltage is exceeded the diode diffuses electrons and holes which carrier electric current. This mechanism helps the diode generate a stable voltage and prevents any permanent damage from occurring.

The 3EZ75D5/TR12 has an optimal reverse breakdown voltage of 5.1V. This means that for every 2.4V worth of current it will generate 5.1V of voltage. When the current is decreased, or reversed, the diode will still generate 5.1V of voltage which makes it a very efficient voltage regulator.

Conclusion

The 3EZ75D5/TR12 is a single Zener diode that is used in various electronic circuits as a voltage and current regulator. Its reverse breakdown voltage of 5.1V gives it the unique ability to both provide current and regulate current. This makes the diode a very effective voltage regulator, as it is able to consistently provide a voltage of 5.1V regardless of the current.
