TVS - Diodes, or Transient Voltage Suppressors, are a type of electrical component that are designed to protect sensitive electronic circuits from voltage spikes. The 5KP85-B is an example of a TVS, and can be used to protect a variety of electronic circuits from high current and voltage transients, often caused by lightning strikes or an electrostatic discharge. In this article, we\'ll discuss the application fields and working principles of the 5KP85-B.

Application Fields

There are a wide variety of applications where the 5KP85-B could be used, including automotive applications, semiconductor protection, ESD (electrostatic discharge) protection, lightning protection, and signal line protection. In automotive applications, the 5KP85-B can be used to protect against electrical surges caused by alternator startup, power window operation, and other transient events. In semiconductor protection, the 5KP85-B can be used to safeguard ICs from damage caused by overvoltage due to transients. In ESD protection, the 5KP85-B can be used to provide rugged protection against electrostatic discharge events, while in signal line protection, the 5KP85-B can be used to protect delicate signals from voltage spikes caused by lightning strikes or over-voltage conditions.

Working Principle

The 5KP85-B utilizes a diode based design that provides low capacitance, rugged protection from both high current and high voltage transients, such as those caused by electrostatic discharge events or lightning strikes. In operation, the diode works to rapidly reduce the voltage between two parts of the circuit. When the voltage between two points in the circuit exceeds the specified level, the 5KP85-B will begin to conduct, quickly reducing the voltage between the two points. This reduces the possibility of irreversible damage resulting from the transient event. The 5KP85-B is designed to be extremely robust, and can withstand high voltage and high current transients without damage to the device.

Conclusion

The 5KP85-B is an example of a TVS, or Transient Voltage Suppressor, and is designed to protect electronic circuits from voltage spikes, often caused by lightning strikes or an electrostatic discharge. The 5KP85-B can be used in a variety of applications, including automotive applications, semiconductor protection, ESD protection, lightning protection, and signal line protection. The 5KP85-B utilizes a diode-based design, which allows it to rapidly reduce the voltage between two points in the circuit, providing rugged protection from high current and high voltage transients.
