MP5KE12CAE3

The MP5KE12CAE3 is a bidirectional Transient Voltage Suppressor (TVS) diode with a 12volt rating. TVS diodes are mainly used for electrostatic discharge (ESD) protection and to clamp over-voltage transients. They are also sometimes referred to as “crowbar diodes”, because they “crowbar” overloaded circuits into protection mode.

The MP5KE12CAE3 is constructed with a zener diode and a high-power MOSFET transistor. This combination of components gives it better surge and ESD protection compared to conventional diodes. The MOSFET inside the diode acts as a low-impedance path, limiting the voltage applied to a device connected to it.

In general, TVS diodes are used in situations where high-voltage transient protection is needed. This includes any system that requires protection from lightning, electrostatic discharge, or other high-voltage effects. These diodes can be used in visible light applications, industrial machinery, medical equipment, computers, and electronic appliances.

The working principle of the MP5KE12CAE3 is fairly simple. When a high-voltage transient is present on the circuit, the diode’s internal zener diode will be triggered, allowing the MOSFET to “clamp” the voltage. This prevents the voltage from passing through the circuit to the device that it is connected to, protecting it from the harmful effects of the excess voltage.

The MP5KE12CAE3 is a versatile and reliable tool to have in any engineer’s toolkit. It can be used in a variety of applications and has superior protection characteristics compared to more traditional overvoltage protection schemes. It is a great choice for engineers who need to design and build systems that need superior protection from overvoltage transients.
