TVS (transient voltage suppressor) diodes are used to protect sensitive electronic components from high voltage, high energy surges of electrical current. The SMBJ150CA-13 is a widely used and reliable surge suppression component of this type of diode. It provides superior over voltage protection in a variety of applications where protection from transient voltage is required.

Applications

The SMBJ150CA-13 is commonly employed in a variety of industrial and consumer applications, notably in the telecommunications, automotive, medical, and computer industries. It can be used to provide protection from failure due to electrical noise, static electricity, or short duration surges. The SMBJ150CA-13 operates in both unidirectional and bidirectional modes, providing balanced protection in either direction. Its compact SMB package allows for easy integration into existing circuit designs.

Working Principle

The SMBJ150CA-13 is based on avalanche breakdown technology. It works by clamping voltage levels, rapidly diverting unwanted current away from components to prevent damage from overvoltage. It utilizes a standard zener diode for breakdown voltage at 6.2-7.2V, and an avalanche limiting resistor of 10.2kohms. When a surge reaches the junction of the zener diode and limiting resistor, the diode changes its characteristics and dissipates the surge energy. This helps reduce the maximum power handled by the device and the power dissipation during normal operation.

The SMBJ150CA-13 is designed to absorb transient surge over voltages and protect electronic equipment from damage. It provides protection against a wide range of surge levels, from 250V to 2000V, depending on the model. The device is highly reliable, with surge life of up to 1000 operations and continuous operating voltage (COV) of up to 6V. It also has an operating temperature range of –65°C to 125°C.

Conclusion

The SMBJ150CA-13 is a widely used TVS diode for surge protection. It offers superior protection from transient surge voltages, and is suitable for many different applications. It operates within a range of maximum voltages, from 250V to 2000V, and can protect components from failure caused by electrical noise, static electricity, or short duration surges. Its small size and wide operating temperature range make it an excellent choice for use in a variety of industrial and consumer applications.
