3KP64-B TVS Diode Application Field and Working Principle

Transient Voltage Suppressor (TVS) diodes are a type of voltage-limiting device that is designed to protect semiconductor components from high voltage transients caused by electrostatic discharge (ESD) or induction. The 3KP64-B TVS diode is a three-lead, low capacitance, uni-polar device that is designed to protect systems from transient voltage events. It has a low breakdown voltage of 6.2V and can handle up to 4kV of surge current.

The 3KP64-B TVS diode has several application fields, including protection against ESD for electronic components and PCBs, overvoltage protection for mobile products, and overvoltage protection for automotive circuits. It is commonly used in the automotive industry, industrial equipment, and consumer products.

The working principle of the 3KP64-B TVS diode is simple. When a transient voltage event occurs, the diode’s anode is connected to the source and the cathode is then connected to the load. During the surge, the current passes through the diode and causes it to clamp or limit the voltage. This way, the high voltage transient is limited to the breakdown voltage and the circuit is protected.

The 3KP64-B TVS diode is a fast reaction device with a reverse recovery time of less than 1ns. It also has low capacitance of less than 1pF and a high surge current capability of up to 4kV. It is a robust device designed to provide transient over-voltage protection for a variety of applications.
