Introduction

2EZ19D5E3/TR12 is a voltage regulator diode that belongs to a family of Zener single diodes. This diode is most often used in applications where a precise voltage reference is needed, such as voltage-controlled oscillators (VCOs). It is typically used to regulate the output of switching power supplies to a precise voltage level, or to maintain a precise reference voltage for other applications such as analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).

Applications

The 2EZ19D5E3/TR12 Zener diode can be found in a variety of applications, primarily as a voltage reference. It is used in power supplies and voltage converters to regulate the output voltage. It is also used in precision voltage references, current sources, and voltage-controlled oscillators (VCOs). Additionally, it can be used in the design of voltage-controlled capacitors and active filters.

Working Principle

The 2EZ19D5E3/TR12 Zener diode is a voltage regulator diode. It operates by controlling the voltage flow between two points in a system. To do this, the diode is placed across a load (in parallel) to the general supply and a current source. When the source voltage is greater than the breakdown voltage of the diode, the diode breaks down and begins to conduct current. This current is then used to regulate the load voltage.In summary, the working principle of the 2EZ19D5E3/TR12 Zener diode can be defined as controlling the voltage flow between two points in a system by using a diode placed across a load. This diode regulates the current, and thus the voltage of the load, through its breakdown voltage.

Conclusion

The 2EZ19D5E3/TR12 Zener diode is a versatile and reliable voltage regulation diode. It can be used in a variety of applications, including voltage converters, power supplies, voltage-controlled oscillators, voltage references, current sources, and more. Additionally, its working principle – controlling the voltage flow between two points in a system by using a diode placed across the load – is a simple, yet effective, way of regulating the load voltage.
