3EZ120DE3/TR8

Diodes are an essential component within an electrical circuit, and are mainly used for providing an easy path for current to move in one direction. Among the many types of diodes is the Zener, which is a special type of diode that allows current to move in either direction, as long as it is below a certain voltage. The 3EZ120DE3/TR8 is one such diode. It is a single Zener diode, and has a variety of applications and working principles.

Technical Details

The 3EZ120DE3/TR8 diode is a single Zener diode that has a 4.3V peak to its Zener voltage and a maximum reverse voltage of 48V. It has a very low dissipation power of 0.35W and a forward voltage drop of 0.3V. It features an operating temperature range of -55 to +155 degrees Celsius, and a storage temperature range of -55 to +175 degrees Celsius. The diode also has a 100mW power rating.

Applications

The 3EZ120DE3/TR8 diode can be used for a variety of applications. It can be used as a voltage reference source in applications such as automotive electronics, power supplies, and analog-to-digital converters. The diode is also suitable for use in overvoltage protection circuits, clamping circuits, and voltage limiting circuits. It can also be used in noise suppression applications.

Working Principle

The 3EZ120DE3/TR8 diode works on the principle of a Zener diode, which is a diode that can be biased so that it becomes a voltage reference source. When the Zener diode is reverse biased, it allows current to move in both directions, but only up to the Zener voltage. Beyond this voltage, the diode will experience a breakdown, and the current flowing through it will be limited. This type of diode is able to remain stable if the current going through it is limited, which allows it to be used as a voltage reference source. In the case of the 3EZ120DE3/TR8, the Zener voltage is 4.3V.

Conclusion

The 3EZ120DE3/TR8 single Zener diode is a versatile and reliable device that can be used in a variety of applications. Its Zener voltage of 4.3V allows it to be used as a voltage reference, and its low dissipation power and forward voltage drop make it suitable for noise suppression and overvoltage protection applications. Its wide operating temperature range means that it can be used in a variety of environments, and its 100mW power rating ensures that it can handle a range of current levels.
