2EZ200D10/TR8

Diodes are an important component in a wide range of electrical and electronic applications. Zener diodes, specifically, are a type of diode that is specially designed to allow a reverse current to flow, even when the bias voltage (the voltage applied to the diode) is below a certain threshold. This is achieved by utilizing a zener breakdown mechanism. The 2EZ200D10/TR8 is a single zener diode with a specified breakdown voltage of 200V. This article will discuss its application field and working principle.

Application Field

The 2EZ200D10/TR8 diode is used in a wide variety of applications, such as in surge suppressors, transient voltage suppressors (TVSs), snubber circuits, and even in power supplies. In surge suppressors, these diodes protect electrical components from high voltage surges by allowing a surge current to flow in one direction and blocking it from the other. The device\'s breakdown voltage of 200V makes it an ideal choice for these applications. In transient voltage suppressors, the diode is used to protect against voltage spikes that could otherwise damage an electronic component. Here, the diode\'s high breakdown voltage ensures that it can handle the high voltages encountered in these systems.

Snubber circuits are used to limit the voltage transients in power systems. The 2EZ200D10/TR8 can be used in these applications due to its ability to withstand high voltages. In power supplies, the diode can be used to act as a clamp, limiting the voltage between two points. This is important for protecting against unwanted voltage spikes. The diode\'s high breakdown voltage makes it ideal for these applications, as it ensures that the diode can handle the high amounts of voltage that power supplies often generate.

Working Principle

The working principle of a zener diode is based on a zener breakdown mechanism. When a zener diode is reverse biased, the electric field in the depletion zone increases. If this electric field exceeds a certain value, it will cause electrons to break away from the covalent bonds in the semiconductor material and form a conducting channel between the p-type and n-type regions. This conducting channel creates a current path which allows a current to flow, even when the diode is reverse biased.

In the case of the 2EZ200D10/TR8 diode, the breakdown voltage is specified as 200V. This means that when the reverse bias voltage applied to the diode exceeds 200V, the zener breakdown mechanism will be triggered and a small current will be able to flow. This current flows in a controlled manner, allowing the diode to act as a voltage limiter.

Conclusion

The 2EZ200D10/TR8 is a single zener diode with a specified breakdown voltage of 200V. It is used in many applications, such as surge suppressors, transient voltage suppressors (TVSs), snubber circuits, and even in power supplies. The working principle of the diode is based on the zener breakdown mechanism, which allows a current to flow, even when the diode is reverse biased.
