TVS - Diodes, also known as transient voltage suppressors, are surge protection devices that are used to help protect sensitive electronic circuits from voltage transients. They are available in many sizes and shapes, but the 5KP190-B is one of the most popular types of TVS diodes. In this article, we’ll take a look at the application field and working principle of the 5KP190-B.

Application Field of 5KP190-B

The 5KP190-B is a unidirectional TVS diode, which means it can only allow electricity to flow in one direction. This diode is typically used in circuits that require protection against transient voltage spikes and surges. It can be used in a variety of different applications, including industrial automation systems, automotive electronics, communications systems, LED lighting systems, and home electronics.

The 5KP190-B has a reverse breakdown voltage of 5kV, and it can also handle surge currents of up to 200A. It has a maximum power dissipation of 500W, and it can operate across temperatures ranging from -55°C to +175°C. This makes it suitable for a range of different applications.

Working Principle of 5KP190-B

The 5KP190-B is designed to protect sensitive electronic circuits from transient voltage spikes and surges, and it is also designed to absorb and dissipate excess energy. When a voltage spike occurs, the TVS diode will “clamp” the voltage to a safe level. This prevents the surge from reaching the sensitive components in the circuit, thus protecting them from damage.

When the 5KP190-B is operating properly, excess energy is absorbed and stored in the diode’s parasitic capacitance. This energy is then slowly released back into the circuit in the form of heat, preventing further damage to the circuit. This is why the 5KP190-B is able to offer such robust surge protection.

Conclusion

The 5KP190-B is one of the most popular types of TVS diode. It is designed to protect sensitive electronic circuits from voltage transients, and it can operate across temperatures ranging from -55°C to +175°C. This makes it suitable for a wide variety of applications, including industrial automation systems, automotive electronics, communications systems, LED lighting systems, and home electronics.

The 5KP190-B works by absorbing and dissipating excess energy, which prevents further damage to the circuit. This is why the 5KP190-B is able to offer such robust surge protection. If you are looking for a reliable surge protection device, the 5KP190-B is an excellent choice.
