Introduction

The 3EZ7.5D/TR12 is a single Zener Diode, designed to help regulate voltage levels by providing a low-impedance path for current, allowing it to bypass other components when voltage drops below the Zener breakdown voltage. The Zener Diode is an important component in circuits when the need arises to regulate voltages or provide protection from transient spikes. By understanding how the 3EZ7.5D/TR12 works and in which applications it can be used, it can be integrated into a variety of designs to help improve system performance.

Applications

One main application is using the 3EZ7.5D/TR12 as a positive voltage regulator, since the Zener allows a current to flow in the reverse direction when the voltage rises above the Zener breakdown voltage. This current flowing in the reverse direction will keep the voltage at the breakdown voltage, creating a regulated voltage source. By adjusting the current and the breakdown voltage, the 3EZ7.5D/TR12 can be used to regulate voltage to the exact level desired. Additionally, it\'s low impedance makes it better suited for this application than other components, such as Transistors, FETs or other Diodes.

The 3EZ7.5D/TR12 can also be used to provide protection from transient voltages or overvoltage spikes. In this application, the diode will conduct current in the normal direction, providing a low impedance path for the spike current to reduce the chances of component damage.

The 3EZ7.5D/TR12 can also be used as a reverse polarity protection devices in battery powered circuits. When the 3EZ7.5D/TR12 is placed in series with the power supply, it will prevent current from flowing in the reverse direction if the battery has been connected in reverse. This helps protect the system from damage in the event the battery is connected incorrectly.

Working Principle

The 3EZ7.5D/TR12 works by using a Zener voltage to regulate the voltage applied across its terminals. The Zener voltage of the 3EZ7.5D/TR12 is specified as 7.5V. This means that when the voltage across the diode exceeds the 7.5V, a current will flow through the diode in the reverse direction, allowing it to bypass other components. This current flowing in the reverse direction will keep the voltage at the breakdown voltage, creating a regulated voltage source.

If the voltage across the 3EZ7.5D/TR12 is lower than the Zener voltage, the diode will act as an open circuit and no current will be allowed to flow in either direction. This is beneficial when used as a protection device, since it will prevent current from flowing when the voltage is excessive.

Conclusion

The 3EZ7.5D/TR12 is a single Zener diode, designed to help regulate voltage levels by providing a low-impedance path for current. It can be used for a variety of applications, including positive voltage regulation, protection from transient voltages or overvoltage spikes, and reverse polarity protection. By understanding the working principle of the 3EZ7.5D/TR12, it can be effectively integrated into systems where voltage regulation or protection is needed.
