Diodes - Zener - Single

The 3EZ11D5E3/TR12 is a single zener diode component commonly used for applications that require stable reference voltages over a wide temperature range. This component is a 3.0V zener diode with a 5% tolerance and a power rating of 12mW. Depending on the application, other voltage levels such as 3.3V, 4V, 5V, and 6V are also available.

Application Field

The 3EZ11D5E3/TR12 has a wide array of uses. The component is commonly used in protection circuits, voltage regulator systems, and bleed circuits. It is also used as a voltage reference where a stable voltage is required or desired. Voltage reference applications are especially good for scenarios in which the component\'s low power consumption is useful, such as in computer hardware and battery operated systems.

Working Principle

A Zener diode is an electronic component that both acts as an electrical conductor and a voltage regulator. The component is made up of a p-type semiconductor in a reverse-biased condition, which creates a junction with a negative voltage potential. The reverse bias creates an electric field, which applies a load to the diode, preventing any greater potential from passing through it. Once a certain voltage threshold (referred to as the Zener voltage) is reached, the current travelling through the component dramatically increases, and the device allows the current to pass through. This Zener voltage acts as a reference, and prevents the voltage from passing beyond it. The 3EZ11D5E3/TR12 in particular is designed to have a 3.0V Zener voltage.

Advantages of the 3EZ11D5E3/TR12

The primary advantage of the 3EZ11D5E3/TR12 is its wide temperature range, making it great for applications that require high consistent voltage levels. Unlike most Zener diodes, the 3EZ11D5E3/TR12 has a tolerance of only 5%, meaning the output voltage can vary by no more than .15V. The component is small in size, with a Marking of 1 giving it an operational temperature range of -65°C to +125°C, making it well suited for a variety of consumer, industrial and other electronics applications.

The 3EZ11D5E3/TR12 is also energy efficient, as it requires no additional energy once the voltage threshold has been reached. This makes it a great choice for uses involving battery operated systems, as the component won\'t use up any more energy than is necessary.

Conclusion

The 3EZ11D5E3/TR12 single Zener diode is capable of providing a stable reference voltage in a variety of applications. It\'s low power consumption and wide temperature range make it an excellent choice for many consumer, industrial, and other electronics applications. In addition, the component\'s small size and high tolerance of 5% make it suitable for use in a variety of dynamic same-voltage applications.
