MP5KE120CAE3

Diode TVS is an acronym for Transient Voltage Suppressors. It is a two terminal device specifically designed to protect circuits from high voltage transients induced by lightning and other disturbances, such as electrostatic discharge (ESD). Diode TVS are unidirectional devices, while Transil devices are bipolar devices. The MP5KE120CAE3 is a typical example of a diode TVS.

The MP5KE120CAE3 is a diode TVS which provides protection to components from fast over-voltage transients, such as those induced by lightning, as well as ESD. The device can sustain repetitive peak currents of up to 1.5A and has an operating voltage of 120V. The device is constructed with a pair of special thyristors inside a metal case, with two leads on the outside. It has an electrostatic protection level of ±25kV, and can withstand transient energy of more than 80 Joules.

The MP5KE120CAE3 is suitable for a variety of applications, including automotive and industrial systems. In automotive systems, it is commonly used in engine control and immobiliser systems, as well as electronic brake control systems. In industrial systems, it can be used to protect circuits from lightning surges or ESD. Additionally, the device is often used in telecom and data protection circuits, and power supply modules.

The working principle of the MP5KE120CAE3 is quite simple. When the voltage level exceeds the device\'s rated voltage, the device quickly conducts the current, thereby limiting the voltage level to protect the electronic components. This is done by creating two thyristors with opposite conductance, making them act as a single switch. These thyristors operate with a fast response time, meaning that the device can respond quickly to over-voltage and short circuit transients.

In conclusion, the MP5KE120CAE3 is a diode TVS which provides protection to components from fast over-voltage transients, such as those induced by lightning, as well as ESD. It is suitable for a variety of applications, including automotive, industrial, telecom and data protection circuits, and power supply modules. The device has an operating voltage of 120V, and its working principle is based on two thyristors with opposite conductance, which act as a single switch.
