Introduction

The 3EZ7.5D10/TR12 series diodes are Zener type diodes mainly intended for use in stabilizing and clipping circuit[s]. The gate also works as a transient voltage suppressor (TVS). In a stabilizing circuit, it provides a reverse voltage regulation point and a stable current flow through the diode. In a clipping circuit, it further adds voltage to the load, thus limiting its voltage.

Application field

The 3EZ7.5D10/TR12 series diodes are mainly used in establishing a stable operating point in an electronic circuit. This is useful for devices and electronic circuits that need a constant voltage level to properly operate. They are also used in transient voltage suppression (TVS) applications, such as phones, computers, or other electronics that may be subject to large voltage transients.

Other applications include overvoltage protection in power supplies, over- current protection in LED lighting systems, limiting inrush current in switched-mode power supplies or other switching power supplies, and protection against electrostatic discharge (ESD).

Working principle

The working principle of the 3EZ7.5D10/TR12 is based on the partial conduction of the semi-conductor material, forming a voltage regulation point in the circuit. In a stabilizing circuit, it will regulate the voltage at a constant level and prevent it from going higher or lower. In a clipping circuit it will add a voltage to the load, which will limit its voltage.

The device also works as a transient voltage suppressor (TVS). It does this by clamping transient voltages greater than a certain level and preventing the device from being damaged. This is especially useful for applications such as phones, computers and other electronics that may be subject to voltage transients.

The 3EZ7.5D10/TR12 series also helps to limit inrush current when switched-mode power supplies are turned on, thus protecting other components in the circuit against damages or failure. It also helps to protect against electrostatic discharge (ESD).

Conclusion

The 3EZ7.5D10/TR12 series diodes are Zener type diodes mainly intended to be used in stabilizing and clipping circuits. They are mainly used to set a stable operating point in electronic devices and circuits, as well as for transient voltage suppression (TVS) applications. Their other applications include overvoltage protection, over-current protection, inrush current limitation, and electrostatic discharge protection.
