MA1.5KE12CA is a part of the TVS - Diodes, which is mainly used in the protection of electronic system from transient overvoltages and ESD. In this article, we will focus on the application fields and working principle of the MA1.5KE12CA.

Application field

MA1.5KE12CA is widely used in the fields of automotive, communication, consumer electronics and industrial control, power supply and so on. It provides quick response characteristics under high surge events, thus protecting the electronic systems from damage or malfunction due to transient voltage or ESD. The MA1.5KE12CA TVS diodes are ideal for protecting AC/DC full bridge and half bridge rectifiers, digital circuits, I²C busses, automotive applications, automotive LED lighting, USB ports, and remote control systems.

Working Principle

The working principle of MA1.5KE12CA follows the general principle of TVS Diodes which is based on the transient absorption mechanism. The MA1.5KE12CA TVS diode device has two junctions in series, and consists of a reverse breakdown voltage, a clamping voltage , a power dissipation and a capacitance. The reverse breakdown voltage is the maximum reverse voltage the TVS diode can withstand before it breaks down. The clamping voltage is the maximum voltage the diode can withstand before it begins to conduct. The power dissipation is the amount of power that can be dissipated through the diode without damage, and the capacitance is the time and charge constant for the TVS diode. When a transient voltage occurs, the TVS diode will absorb it by quickly turning on from an off state. By doing so, it effectively limits the transient voltage from travelling into the protected system, protecting it from any possible damage. This is why it is used in many applications where over voltage protection is necessary.

Conclusion

The MA1.5KE12CA is a versatile TVS - Diodes which can be used in many application fields such as automotive, communication, consumer electronics and industrial control, power supply and so on. It works by quickly turning on with the occurrence of a transient voltage, aborting its travel to the protected system and thus protecting it from any possible damage.
