MSMBJ12CAE3

TVS - Diodes

The MSMBJ12CAE3 is a component in the category of transient voltage suppression (TVS) diodes. TVS diodes are used to protect electronic circuits from unwanted power transients, or "spikes" in voltage. They have a wide variety of uses and can be found in a range of applications, from automotive systems to consumer electronics.

Application Field

The MSMBJ12CAE3 is a high-power uni-directional TVS diode, designed to provide protection against electric transients caused by lightning strikes and those generated by inductive switching circuits. It is suitable for high-voltage, high-energy applications, such as power supplies, telecommunication lines, and motor control circuits. It is widely used in industrial and automotive applications, as well as in consumer electronics.

Working Principle

When an electric transient occurs, the TVS diode will conduct a large current, shorting out the voltage spike and thus protecting the circuit. The MSMBJ12CAE3 has a reverse breakdown voltage of 12V, and a peak pulse power of 600W. When the voltage exceeds this level, the diode will start to conduct and absorb the excess power; the device will then cool off and reset itself, ready for the next transient.

Other Features

The MSMBJ12CAE3 also has several other features which make it well-suited for industrial and automotive applications. It has a low capacitance of less than 50pF, which minimizes switching noise and reduces interference with other components. The design of the diode also makes it resistant to ESD (electrostatic discharge). This means that it can withstand surges of up to 8KV without damage.

Overall, the MSMBJ12CAE3 offers an ideal solution for protecting circuits from power transients, making it an essential component for ensuring the reliability of any electronic system.
