TVS - Diodes: 5KP190A-B Application Field and Working Principle

TVS (Transient Voltage Suppressor) diodes are a type of semiconductor device designed to provide protection against high-energy transients. They are typically placed between a component and the power supply or ground, and can be configured to be used in a variety of ways. The 5KP190A-B is a type of TVS diode with some unique features and applications.

Features of 5KP190A-B TVS Diodes

5KP190A-B TVS diodes are designed for reverse stand-off voltage values of 24V, 30V, 40V, and 49V. With 400W power dissipated with high surge currents, these diodes are rated to be able to protect against transients as high as 5KV. These diodes are UL certified, and provide a number of features that enable effective protection, such as low clamping voltage, fast response time, and large amounts of ESD protection.

Applications of 5KP190A-B TVS Diodes

The 5KP190A-B TVS diode is used in a wide variety of applications, from industrial protection to consumer electronics. This type of diode is especially popular in automotive electronics, where it is used to protect a vehicle’s sensitive electronic components from voltage transients. As they are rated to be able to protect against high surge currents and transients, they are ideal for applications that require high reliability and long lifetimes. Other common applications include medical devices, data devices, and communications systems.

Working Principle of 5KP190A-B TVS Diodes

The working principle of a TVS diode is relatively straightforward. When a voltage transient is detected, the diode will conduct current in the reverse direction. This current does not damage the component as it will be directed away from the component and dissipated as heat. Due to the diode’s ultra-fast response time, it is able to protect against transients as they occur, and will limit the amount of voltage that is allowed to pass through the system.

Conclusion

The 5KP190A-B is a type of robust and reliable TVS diode that offers a number of features and applications. With its high surge current and low maintenance cost, it is an ideal choice for a variety of different protection requirements. With its fast response time and ESD protection it is perfect for protecting sensitive components from voltage transients.
