TVS (transient voltage suppressor) diodes are a type of protection component used in the electronics industry to protect different components and boards from excessive voltage and current. The CR1402AB is a popular TVS diode with an application field in various types of electronic equipment, such as computers, telecommunications, and consumer electronics.

Working Principle

The CR1402AB works on the principle of reverse biased diode breakdown. It is essentially two diodes connected back-to-back in the same package. When the reverse voltage exceeds a preset threshold, the two junctions break down and the device starts to conduct current. This makes it an ideal solution for protection against voltage transients.

The device has a fast reaction speed that allows it to quickly clamp the voltage rise when a transient occurs. This prevents damage to the protected component and board. It also has a high surge capability that can handle large surges of current, which make it suitable for high-current applications.

The CR1402AB also has a low reverse leakage current, which is important for applications that require a low level of power consumption. Additionally, its package size is small and relatively easy to mount on a board, which makes it ideal for space-constrained applications.

Applications

The CR1402AB has a wide range of applications that make it suitable for many types of equipment. It is used in automotive, industrial, telecom, and consumer electronics applications, as well as in military, aerospace, and other specialized applications.

In automotive applications, it is used to protect against overvoltage, ESD, and EMI protection, and to prevent damage to electrical components due to power surges. The device is also used to provide protection against voltage transients in industrial applications, such as power supplies, motor control, and renewable energy systems.

In telecom applications, the CR1402AB is used to protect high-speed data lines, such as USB ports and Ethernet lines, as well as to reduce conducted and radiated EMI. In consumer electronics, it is used to provide protection to audio and video equipment, such as televisions, DVD players, and digital cameras.

In addition, the device is used to provide ESD, EFT, and EMI protection in military, aerospace, and other specialized applications. Its fast response time and small package size makes it ideal for these applications, where space is at a premium.

The CR1402AB is a reliable, cost-effective, and easy-to-use device that can be used in a wide variety of applications. Its fast response time, low reverse leakage current, and high surge current capability make it an ideal choice for protecting electronic components against voltage transients.
