MA5KP6.0CAE3 Application Field and Working Principle

Electronic devices such as computers, mobile phones, and tablets, generally use metal oxide varistors (MOVs) to protect against electrostatic discharge (ESD). MOVs limit the voltage spike seen by a other components when ESD is present, and their properties are determined by the material composition of the MOV. The MA5KP6.0CAE3 is the latest addition to a range of MOVs manufactured by Bourns Inc. This device is designed to protect high-speed data lines in a variety of applications, from automotive to consumer-level electronics.

The MA5KP6.0CAE3 is a non-polar MOV, meaning that it does not require any additional components to ensure the correct connection of an ESD protection circuit. This MOV contains a Zener diode for enhanced ESD performance and is rated to handle up to 6KV, far exceeding the 8KV of its predecessor. Being of a non-polar construction, the MOV does not require the user to determine the direction of the surge voltage before inserting the component. The MOV also has an impressive low leakage current of only 0.9mA at rated standoff voltage.

The working principle of the MOV can be explained using the basic diode equations. In the presence of an ESD event, electrons are forced to move across the dielectric material due to the increased electric field. As the applied voltage increases, the current flow rate through the MOV also increases exponentially (following the diode equation). At some point, the MOV becomes saturated, meaning that the MOV will not absorb any further charge and the excess energy is shunted around the circuit. The purpose of this is to protect the other components in the circuit from damage due to excessive voltage. Additionally, the MOV can be designed to react to variations in current, allowing for a higher level of protection.

The MA5KP6.0CAE3 provides enhanced protection against ESD events compared to other MOVs, making it a suitable option for a variety of consumer-level electronics. Furthermore, the device has an impressive low leakage current, allowing it to provide a higher level of protection for sensitive data lines. As such, the MA5KP6.0CAE3 is a high performance MOV that is suitable for a variety of applications.
