TVS – Diodes

Transient Voltage Suppression (TVS) diodes, also known as surge-suppression diodes or surge absorbers, are circuit protection devices designed to protect electrical and electronic components from potential overvoltage events such as those generated by lightning, motor starters, and so on. TVS diodes work by limiting the voltage from the source, diverting it to ground. This limits the potential damage from a surge or overvoltage.

20KPA80-B Application Field and Working Principle

The 20KPA80-B is a unidirectional, fast-acting TVS diode rated for a maximum peak pulse power of 485W. It is a small-size, compliant ESD protection diode, suitable for protection against lightning, electrostatic discharge, and overvoltage events. This type of TVS diode with a bidirectional current capacity is ideal for use in 5G networking, automotive, military, industrial, and other high-power applications.

The 20KPA80-B is designed to protect against both overvoltage transients and electrostatic discharges. It\'s rated for a maximum peak pulse power of 485W and a junction capacitance of 8pF. The diode works by limiting the voltage from the source, diverting it to ground, and shunt any transient energy to ground before it can reach the protected device. This limits any potential damage from an overvoltage or electrostatic discharge. The diode also has an integrated clamping voltage which engages when there is an overvoltage to ensure the safe operation of the protected device.

The 20KPA80-B is not only resistant to electrostatic discharges in the sense of typical ESD testing, it also has additional protection for the system, due to the integrated internal clamping voltage. This clamping voltage is the voltage level that the TVS diode will activate and start to restrict the voltage path to ground. This ensures the device being protected can remain energized while at the same time be prevented from overvoltage.

The 20KPA80-B is designed to be used in a variety of applications, where transient overvoltage protection or ESD protection is required. Examples of such applications include LCD panel protection, transceiver protection, compressor protection, and power conditioning systems. This TVS diode can also be used in wireless systems such as Wi-Fi, Bluetooth, and WLAN, as well as any other circuit requiring ESD protection and overvoltage protection.

In summary, the 20KPA80-B is a fast-acting, unidirectional TVS diode with a maximum peak pulse power rating of 485W. It is designed for applications requiring transient overvoltage protection or ESD protection, such as LCD panel protection, transceiver protection, compressor protection, power conditioning systems, wireless systems, and so on. The diode is integrated with an internal clamping voltage which activates in case of an overvoltage, ensuring the safe operation of the protected device.
