Varistors, MOVs and other Transient Voltage Suppressors (TVS) are used to protect sensitive electronic components from damage due to voltage spikes, transients or other voltage irregularities. The CGA0603MLC-12E is a surface-mount TVS device designed to provide excellent protection for sensitive electronic circuits against voltage transients. It is a bi-directional, non-polarized device that provides excellent protection for a wide range of applications, from low amplitudes to very high frequency transients.

The CGA0603MLC-12E is made of a high-temperature resistant polymer-based material that provides excellent thermal stability and durability. The device is available in a tiny surface-mount package, making it ideal for high-density circuit protection applications. The device is open-circuit when subjected to transients, but does not interfere with normal circuit operations. Its non-polarized design allows it to be used in AC and DC applications, and its high voltage rating makes it suitable for a wide variety of electronic applications.

The application field of the CGA0603MLC-12E includes automotive electronics, cell phones, telecommunications, and computers. The device is capable of protecting against overvoltage in automotive applications, such as discharging of empty capacitors on the printed circuit board. In cell phones, it can protect against the voltage spike caused when the user plugs the charger into the device. In telecommunications, it can protect against lightning and electrical interference, while in computers it can protect against electrostatic discharge damage.

The working principle of the CGA0603MLC-12E is based on the theory that an impulsive current generates a voltage across a material with a resistor–capacitor (RC) or resistor–inductor response. This effect, known as the "RC effect," creates a built-in voltage clamp that limits the voltage spike. The CGA0603MLC-12E has a built-in device that reduces this voltage spike and protects sensitive circuits. This process occurs when an impulsive current generated by a voltage transient is generated; the device reduces the peak voltage by clamped the waveform.

The CGA0603MLC-12E can be used in a variety of applications ranging from low-amplitude to very high-frequency transients, making it a versatile choice for voltage protection. The aluminium-nitride-based technology in the device gives it superior electrical performance and thermal stability, making it suitable for use in a wide range of environments. Furthermore, its very thin profile and low-profile allows for ease of use in a multitude of electronic projects.
