SMAJ12CA-Q

TVS - Diodes

TVS or Transient Voltage Suppression diodes are components widely used in electronic circuits and used for protection against electrical surges. The SMAJ12CA-Q is a particular type of TVS diode with protection capabilities of up to 12A current and 1500W peak power. It is a unidirectional diode with two terminals and a reverse stand-off voltage of 12V.

Applications

The SMAJ12CA-Q is used in a variety of applications. It can be used in the automotive industry, protecting components from over-voltage and transients caused by various sources, such as lightening. It is also suitable for powering electrical equipment in power systems such as solar power systems and other home automation and industrial control systems. Additionally, it can be used in general overvoltage protection and transient protection, helping components from signals that are too high or too low for a normal operation.

Working Principle

The SMAJ12CA-Q works in a similar way as other TVS diodes. The two terminals are connected to the electrical circuit, and the reverse breakdown voltage of 12V is reached when the current passes through the diode above a certain level. Once the voltage reaches 12V, the current is suppressed, preventing any damage to the circuits. The device can clamp the voltage, allowing the current to go either back to the source or to a ground. This is how it works in protection against transients.

Conclusion

The SMAJ12CA-Q is a highly reliable and efficient TVS diode. It is suitable for working with a wide range of operating voltages and can easily withstand transients and surges of up to 12A current and 1500W peak power. Moreover, it is used in a variety of applications, from the automotive industry to solar power systems. The device follows a simple working principle, where the voltage is clamped and the current is suppressed once it passes the reverse breakdown voltage level.
