A TVS (Transient Voltage Suppressor) diode, also known as a transient suppressor, is a device designed to limit transient voltages. CR4802AB is a bidirectional Transient Voltage Suppressor (TVS) diode designed with avalanche technology to offer - very low break down voltage (<10V), low clamping voltage (<20V) and excellent transient protection performance.

The CR4802AB offers excellent various application fields, such as providing surge protection for automotive electronics, computers, and batteries etc. The device is also suitable for ESD surge protection to enhance the reliability and safety of the system. Nowadays, CR4802AB has been widely used in LCD displays, digital cameras, automotive onboard electronics and many other digital devices and systems.

When the input voltage exceeds the breakdown voltage of CR4802AB, it will turn on quickly and conduct current to protect the device. The working principle of CR4802AB is to suppress the surge and clamp the voltage to a safe level with ultra-low leakage current. When it reaches a clamping voltage, CR4802AB will conduct current until the voltage level returns to within the allowed range.

Due to its ultra-low clamping voltage, CR4802AB is capable of clamping voltages in the nanoseconds range, ensuring no disruption or interference to the system operation. In addition, it can handle a continuous high surge capacity with a maximum surge current rating up to 10A. Therefore, CR4802AB ensures the reliability of the device operations and the safety of the system.

The high surge capability of the CR4802AB enable it to provide reliable over-voltage suppression and fast-response protection from both positive and negative voltage transients, making it a reliable choice for many applications. Moreover, it is also available in various package sizes and voltage ratings, which can meet different protection requirements.

In conclusion, CR4802AB is an ideal choice for different application fields such as LCD displays, digital cameras, automotive onboard electronics and more. With its ultra-low breakdown voltage, low clamping voltage, and high surge capability, it ensures efficient protection for the system. Furthermore, its small size and various package options are also essential factors for its application.
