TVS - Diodes: 15KPA43A-HR Application Field and Working Principle

TVS - diodes, sometimes referred to as Transient Voltage Suppressors, are devices that help protect sensitive electronic components from overvoltage transients, such as those that occur during lighting storms or power surges. They are commonly used as protection for data ports, power supplies, and other sensitive components. The 15KPA43A-HR TVS diode is a commonly used device in many circuits and systems.

Function

TVS diodes act as a one-way valve that allows current to flow in just one direction. When an overvoltage occurs, the diode will quickly and efficiently pull weak current away from the sensitive electronic components it is protecting and will act as a temporary voltage drop. This voltage drop helps reduce the surge and subsequent damage to the sensitive components.

Applications

The 15KPA43A-HR TVS diode can be used in a variety of applications where protection from transient surges of voltage is needed. These include computer and peripheral equipment, digital cameras, audio/video equipment, telecommunication systems, medical device, automotive system, and industrial equipment. The 15KPA43A-HR is an ultra-low capacitance bidirectional transient voltage suppression diode. It is designed to protect high-speed data lines from voltage threats and is ideal for protecting sensitive ports such as USB 3.0, HDMI, and DisplayPort.

Working Principle

The 15KPA43A-HR TVS diode works by using a reverse breakdown voltage to quickly clamp down the voltage when it rises above a certain level. When the voltage rises above the breakdown voltage, the diode will quickly switch to a conductive state and pull the voltage back down to a safe level. This helps protect the sensitive electronic components from the surge in voltage. The reverse breakdown voltage of the 15KPA43A-HR device is 15kV. It has a low capacitance of 0.2pF and provides excellent ESD protection of up to 8kV human body model (HBM).

Conclusion

The 15KPA43A-HR TVS diode is a popular and reliable device used in many different types of circuits and systems to protect sensitive electronic components from transient voltage spikes. It is a one-way valve that allows current to flow in one direction, and when an overvoltage occurs, the diode will quickly and efficiently pull weak current away from the sensitive components. The 15KPA43A-HR has a reverse breakdown voltage of 15kV and its low capacitance provides excellent ESD protection of up to 8kV HBM. It is ideal for protecting high-speed data lines and can be used in a variety of applications.
