Application Field

The 1N5344E3/TR13 diode can be used to plateau voltage across loads, while being able to maintain a stable voltage below the breakdown voltage. It is often used as a voltage regulator, or as a reference voltage source, to control the voltage in circuits. Due to its wide temperature range, it is also frequently used in automotive, industrial, and military electronic systems. Additionally, they are used in feedback control circuits to limit current spikes, and can also be used to maintain a stable voltage in switching power supplies.

Working Principle

A Zener diode is a special type of diode, designed to conduct current in both forward and reverse bias conditions. Most of its uses are as a voltage regulator, as it has a low and predictible breakdown voltage, known as the Zener breakdown voltage. When forward-biased, it will allow a current through in the same manner as a regular diode, However, when the diode is reverse-biased the electric field strength is increased to the point at which the diode begins to allow current through, known as the Zener breakdown voltage.

When the diode reaches this voltage, it is said to be in reverse-breakdown, and will continue to allow current to flow, as long as the voltage remains above the Zener breakdown voltage. This allows the diode to act as a voltage regulator, as it will remain at the Zener breakdown voltage, regardless of an increase in voltage across the diode. The diode will also limit the voltage of a current as it passes through, ensuring that the voltage and current remain at predefined levels.

Conclusion

In conclusion, the1N5344E3/TR13 diode is a single Zener diode that is part of the 1N53xx family of Zener diodes, with a wide application field in voltage regulation or reference voltage sources. Its working principle relies on Zener breakdown voltage to regulate or limit voltages in a circuit.
