TVS (Transient Voltage Suppressor) diodes are essential components of any circuit that requires protection from extreme voltage spikes. The SMBJ90A-13 device is an example of a TVS diode designed specifically for protection. It is highly capable of providing circuit protection from overvoltage transients resulting from lightning strikes and other sources of high voltage. The device has a low breakdown voltage and fast response time. In this article, we will outline the SMBJ90A-13\'s application field and working principle.

The SMBJ90A-13 is used in a variety of applications including automotive electronics, industrial equipment, telecommunications, and medical devices. The device is designed for general use as ESD protection. It offers robust ESD protection up to 25A and has a breakdown voltage rating of 13V. It also features a very fast response time and low clamping voltage. The SMBJ90A-13 is especially suitable for protecting sensitive circuitry found in automotive systems.

The device has a working principle based on the Zener effect, where the breakdown voltage is determined by the doping concentration of the semiconductor material. When the external voltage applied across the device exceeds the breakdown voltage, the electrons begin to become more mobile and form a current channel, thus allowing the current to pass. The device then clamps the voltage, limiting the current to a safe value. The SMBJ90A-13 has an excellent clamping capability, making it ideal for applications where the circuit must be protected from high voltage transients.

In summary, the SMBJ90A-13 is a versatile TVS diode suitable for a wide range of applications. The device has an excellent breakdown voltage and fast response time, making it a reliable choice for protecting sensitive systems from high voltage transients. The device operates based on the Zener effect, clamping the voltage when it exceeds the breakdown voltage rating. The device has become a popular choice in many automotive and industrial applications.
