TVS - Diodes

TVS diodes are designed to provide protection from voltage surges that can occur in a circuit. They are often used in situations where the voltage surge is more than expected, such as power supplies, electrical systems, motors, and other electronics. TVS diodes are typically used in automotive and medical applications, and have become increasingly popular for industrial and commercial applications.

3KP70A-B Application Field and Working Principle

The 3KP70A-B is a specialized TVS diode designed to protect sensitive electronics from damaging electrostatic and electrical transients. It is designed to provide protection from over-voltage transients of up to 70V and up to 5000A. The 3KP70A-B is typically used in automotive, medical, and industrial applications where protection from a wide range of voltage and current values is needed.

The working principle of the 3KP70A-B is simple. When the voltage levels of an electrical system exceed the diode’s rated voltage, it will become conductive and rapidly release the excess voltage into the ground. This will limit the surge to a safe level and prevent it from causing damage to sensitive components. The diode will then return to its non-conductive state as the voltage drops back to its rated voltage.

In addition to providing surge protection, the 3KP70A-B also provides ESD protection and over-voltage protection. By clamping any ESD surges to a safe voltage level, it ensures that sensitive components are not damaged by ESD events. It provides over-voltage protection by limiting the maximum voltage to a safe level and ensuring that no components are damaged by voltage spikes.

The 3KP70A-B is a robust and reliable TVS diode with a wide range of applications. Its reliable operation and high surge protection capability make it a popular choice for a variety of applications where voltage and current spikes need to be quickly and reliably controlled.
