TVS (transient voltage suppressor) diodes are essential in the protection of several components, circuits, and systems from voltage transients. The MRT100KP220CAE3 is one of the most common TVS-diode components. As such, it has a wide range of application fields, and the knowledge of its operational principle is essential to understand the reasons its being utilized.

MRT100KP220CAE3 Application Field
The MRT100KP220CAE3 is mainly used in I/O protection circuits, where the diode is capable of withstanding transients of up to 220 volts. The component has a working temperature between -55°C and 125°C, and can provide up to 100 kilo-amps (kA) of peak protection for 8µs. This makes it ideal for industrial, automotive, and commercial usage. Additionally, the TVS-diode device is also suitable for protection during electrostatic discharge (ESD) and solar panel operation protection.

MRT100KP220CAE3 Working Principle
When utilized in the protection of sensitive components, the MRT100KP220CAE3 takes advantage of the reverse-biased diode action. At standard operating conditions, the diode is reverse-biased and exhibits a voltage drop of around 0.7v. This drop remains mostly constant no matter how high is the current passing through. However, if a transient voltage spike comes into play, the diode voltage becomes saturated. During this process, the protection element works by providing a extremely low impedance path for the passage of the surges currents.

In order to work properly, the device must be properly placed across the line it is supposed to the protect. When the voltage across it goes above certain threshold, the diode will turn on and clamp the voltage associated the with transient immediately and efficiently. Following the decay of the transient, the diode will reset automatically. The effectiveness of this process is owed to the high peak clamping voltage of the MRT100KP220CAE3.

By taking advantage of the reverse-biased diode action, the MRT100KP220CAE3 provides unparalleled direct voltage and ESD protection, allowing it to be utilized in the security of a variety of components in the industrial, automotive, and commercial fields. Thanks to its high peak clamping voltage of up to 220 volts, its working temperature range, and its peak current withstanding capabilities, the MRT100KP220CAE3 is a highly reliable way to protect sensitive electronic components from unexpected voltage transients.
