BZG04-56TR

TVS - Diodes are among the most important components in protecting circuit boards from voltage transients. BZG04-56TR is one of the widely used TVS - Diodes due to its superior performance and high level of protection. This article will discuss the application field and working principle of BZG04-56TR.

Application Field of BZG04-56TR

The BZG04-56TR TVS diode is mainly used in overvoltage, overcurrent, and over temperature protection applications. It offers unidirectional protection, meaning it only protects a circuit against a rising voltage spike. The protection range of the BZG04-56TR is between 5 and 60V with a tolerance of +/- 8V. It also has an operating temperature range of -55ºC to +125ºC and a surge capacity of up to 400A, making it very reliable for both industrial and automotive applications.

The BZG04-56TR can be used in a wide range of devices, such as consumer electronics, printers, telecommunications systems, automobiles, and medical equipment. In particular, its high surge capacity makes it an ideal choice for automotive applications, where it can protect against extreme voltage spikes as well as over temperature conditions.

Working Principle of BZG04-56TR

The BZG04-56TR TVS diode works by clamping the voltage level to a predetermined value. This protects the device from overvoltage and overcurrent conditions. In order to achieve this, the diode is constructed using a p-n junction. When the voltage exceeds the threshold voltage, the p-n junction will be reversed biassed and the diode will start to conduct. This will allow a large amount of current to flow through the diode, thus protecting the device from damage due to overload.

The BZG04-56TR is a very efficient and reliable TVS diode due to its high surge capacity and low voltage drop. It also has a wide operating temperature range, making it suitable for a wide range of applications. Overall, the BZG04-56TR is an excellent choice for protecting circuit boards from voltage transients.
