Introduction

BZX85C22-TR is a type of diode that is used in a variety of applications. This type of diode is known as a single zener diode, and it has a number of advantages over other types. It is small in physical size, has excellent stability, and can be used in a wide range of conditions. In this article, we will discuss the application field and working principle of BZX85C22-TR.

Application Field

BZX85C22-TR is typically used in a variety of electronic circuits that require a steady voltage flow, such as in power conditioning, regulating and stabilizing circuits. Common examples include high voltage/high current protections, voltage regulators, and inverter protection. It can also be used to protect integrated circuits from transient overvoltages, and to protect data communication interfaces, such as coaxial cables and twisted pair cables, from being damaged by voltage spikes. In addition, BZX85C22-TR can provide protection from overvoltage conditions, such as lightning/electromagnetic pulses, as well as circuit protection from false triggering. It is also widely used in medical devices, such as for monitoring patient neurological signals.

Working Principle

BZX85C22-TR is a single zener diode. The working principle of a single zener diode works off the basic principle of the p-n junction diode. When a diode is connected to a voltage supply, a certain amount of current will flow through it. The current flow through the diode can be altered by varying the voltage that is applied. For single zener diodes, they have a specific voltage that they operate at. This is known as the zener voltage, and is determined by the voltage of the device. When a voltage greater than the zener voltage is applied to the diode, the current will switch to a lower level of flow, and remain at that level. This allows the circuit to have a steady and regulated output voltage.

Conclusion

BZX85C22-TR is a type of single zener diode that is used in a variety of applications. This type of diode is small in size and very stable, allowing it to be used in many different conditions. It is used in devices such as power conditioning, voltage regulation, and inverter protection. It also provides protection from transient overvoltages. The working principle of single zener diode relies on the p-n junction diode, which allows the current flow to be altered by varying the applied voltage.
