3EZ30D5/TR8 Application Field and Working Principle

Diodes are an important part of electronics engineering. Like other components on an electronic circuit, they can be classified in different ways. Among them, the Zener series is of special importance, as well as the single types within this series. A good example for single Zener diode is the 3EZ30D5/TR8, which will be the focus of the following article.

Application Field

The 3EZ30D5/TR8 is suitable for general purpose use and can be applied in low-voltage circuits that require logic-level reference signals. It is well suited for applications such as voltage references, voltage regulator/clamp, voltage and temperature protection, and oscillator/mixer circuits. It is also suitable for use in any circuit requiring a static bias element and in television-protection circuits.

Features

The 3EZ30D5/TR8 offers a range of features that distinguish it from comparable products. It has a wide operating temperature range of -65C to 150C, allowing for reliable operation in extreme environments. The device has a low forward voltage drop at lower currents and is ideal for use in low-voltage circuits. In addition, it has a current-regulating capability, allowing it to serve as a voltage clamp or voltage regulator.

Working Principle

The 3EZ30D5/TR8 functions as a rectifier element in its basic form. When reversing biased, it blocks current in the reverse direction while allowing current to flow in the forward direction. The device has two distinct operating regions: avalanche breakdown region and Zener breakdown region. When biased in the avalanche region, the diode’s voltage drop reduces as current passes through it, allowing the diode to regulate current. In the Zener breakdown region, the diode’s voltage drop does not reduce with increasing current, allowing it to clamp voltages.

Conclusion

The 3EZ30D5/TR8 is a versatile, single-Zener diode that can be used in a variety of low-voltage applications. Its low forward voltage drop, operating temperature range, and current-regulating capability make it uniquely suitable for many types of circuits, such as voltage references, voltage regulators, voltage clamps, temperature protection circuits, and oscillator/mixer circuits. Through understanding the device\'s application field and working principle, engineers will be able to accurately and safely select appropriate diodes for their projects.
