Transient Voltage Suppression (TVS) diodes are used to protect circuit from voltage transients.A 3KP20-B diode is a common type of TVS devices used in a variety of applications to protect circuits from transients induced by electromagnetic in nature.

3KP20-B is a glass passivated surface mounted junction, string chipped bidirectional transient voltage suppressor diode specifically designed to protect voltage sensitive components from electrical transients induced by lightning and other sources.It has a peak power rating of 300W, an 8/20μs transient overload pulse of 20kA (typical) and working frequency up to 5MHz. 3KP20-B TVS devices have a working voltage range of 6.0V to 20V. This level of protection provided makes it ideal for sensitive computing and communication applications.

The working principle of 3KP20-B combines a thyristor and a diode component in a single package. The device will clamps down the transient voltage as soon as it exceeds a specified voltage levels. The device starts to conduct as soon as the transient voltage level reaches the breakover voltage. As long as the voltage is higher than the breakdown voltage, the thyristor will keep running until current reaches a predetermined limit. Once the transient voltage fades, the device will go back to nonconductive state. This provides effective protection of the components in the circuit.

The 3KP20-B device is commonly used in various applications, such as line protection for telecommunications, networking, computing, instrumentation, automotive and medical equipment. They are also used in motor control, audio and switch control, network and power line protection, and protection from ESD, EFT and lightning surge. In addition, 3KP20-B devices are used in consumer electronics, solar and renewable energy systems, and industrial automation as well.

3KP20-B TVS devices have excellent clamping and low leakage current properties. They operate at low operating voltage and have wide working power range making them ideal for use in a variety of applications. They are also easy to install with their surface-mount design and can withstand harsh environmental conditions.

In summary, 3KP20-B devices combine the qualities of a thyristor and diode in a single package, protecting components from electrical transients induced by lightning and other sources. The device is efficient, reliable and easy to install, making it suitable for applications including telecommunications, networking, computing, instrumentation, automotive and medical equipment.
