SMBJ7.0CD-M3/H Circuit Protection

TVS (Transient Voltage Suppressor) diodes are semiconductor based components which protect electronics circuits from transient surge voltages and electrical noise. The SMBJ7.0CD-M3/H is one such TVS diode which is particularly well-suited for use in automotive applications. This article will discuss the application field and the working principle of the SMBJ7.0CD-M3/H.

Application Field

The SMBJ7.0CD-M3/H TVS diode is mainly used in automotive applications, such as automotive engines, modules, headlamps, and airbag systems. It is designed to protect automotive electrical and electronic components in both high and low voltage environments. Thanks to its low capacitance and low leakage current, it is suitable for high frequency applications as well. The SMBJ7.0CD-M3/H is also designed to withstand harsh operating environments, making it ideal for use in automotive applications.

Working Principle

The SMBJ7.0CD-M3/H is a unidirectional TVS diode. It blocks reverse current while allowing forward current flow. The device acts as a voltage clamp, limiting the surge voltage to the breakdown voltage of the device. The device is capable of dissipating large amounts of instantaneous power in the event of a high voltage surge. The reverse leakage current increases slowly with the increase of reverse voltage, meaning that it can absorb larger amount of energy than regular diodes.

The SMBJ7.0CD-M3/H is designed with a number of safety features which are essential for use in automotive applications. It is equipped with overvoltage protection to ensure that the circuit is not damaged during a surge event. Additionally, it has built-in thermal protection to prevent overheating during a surge event. It is also designed with a fast response time to ensure that it is able to protect the circuit quickly.

In summary, the SMBJ7.0CD-M3/H is a TVS diode which is designed for use in automotive applications. It is designed to limit the voltage during a surge event and also to absorb large amounts of energy without damage. Its safety features make it a reliable solution for automotive surge protection.
