Introduction to 2EZ4.3D5/TR12

2EZ4.3D5/TR12 is a single Zener diode component that can be used in a variety of applications. It is typically used in circuits where high-voltage protection is needed and noise immunity is required. The component has a maximum reverse voltage of 12 volts and a maximum power dissipation of 500 mW. The component also has a breakdown voltage of 4.3 V.

2EZ4.3D5/TR12 Application Field

The 2EZ4.3D5/TR12 component has a wide range of applications. It can be used for voltage regulation, over-voltage protection, transient protection, and reverse polarity protection. Additionally, the component can be applied in radio frequency (RF) circuits, such as in receiver radios, where it can limit the maximum voltage across the components of the receiver, as well as provide a “ground” connection. It can also be used in power filters, where its low impedance characteristic allows it to form an effective high-pass filter.

2EZ4.3D5/TR12 Working Principle

The 2EZ4.3D5/TR12 component operates on a Zener diode principle. When a voltage that is higher than the Zener voltage is applied, the component exhibits a breakdown, or avalanche, effect. This effect causes a decrease in the resistance of the component and a corresponding increase in the current flow, which is referred to as avalanche current. This effect is what allows the component to supply a steady voltage level, regardless of the voltage applied across its inputs. The Zener diode’s breakdown voltage is determined by several factors, including the junction temperature and the width and depth of the diode’s depletion layer. As the applied voltage increases, the breakdown voltage also increases, until it eventually reaches its saturation level, which is typically higher than the breakdown voltage. In the 2EZ4.3D5/TR12 component, the breakdown voltage is 4.3 volts, while the maximum reverse voltage is 12 volts. This means that the component can withstand voltages up to 12 volts and still retain a stable output voltage.

Conclusion

2EZ4.3D5/TR12 is a single Zener diode component that can be used in a variety of applications. It has a variety of applications, such as voltage regulation, over-voltage protection, transient protection, and reverse polarity protection. The component operates on a Zener diode principle, where it exhibits a breakdown effect when a voltage above its breakdown voltage is applied. This allows the component to supply a steady voltage level, regardless of the voltage applied across its inputs. The maximum reverse voltage of the component is 12 volts and its breakdown voltage is 4.3 volts.
