The CG0603MLA-26KE is an electrical component used to prevent system failures or damages due to electrical overstress. It belongs to the TVS (transient voltage suppression) family of Varistors (voltage-variable resistors), MOVs (metal oxide varistors) and Polymer PTCs (positive temperature coefficient). It is designed to protect electrical systems from fast transient overvoltage events.

This device is characterized with high voltage clamping and low clamping voltage coefficients. Its compact 603 package size is a particular advantage for space-constrained applications. It is suitable for consumer electronics, telecom equipment, automotive, industrial, medical, and lighting applications.

CG0603MLA-26KE devices are built with silicon oxide (SiO2) as the primary dielectric. This results in improved performance and long-term reliability when it comes to transient suppression. The MOVs that form the primary operational structure of this device has a minimum breakdown voltage of 26V, capable of withstanding up to 10KA of transient peak pulse current.

The working principle of CG0603MLA-26KE is simple. In normal functioning situations, the device has a low impedance to voltage. When the voltage or current reaches a higher than normal level, the device increases its impedance and clamps the electrical surge in a manner that prevents system damage. This is done by utilizing its high peak pulse current rating to ground potential.

The high peak pulse current rating is determined by its effective clamping voltage. In other words, the device is designed to effectively – and quickly – reduce excess voltage and prevent system damage. The clamping voltage is indicated by the letter ‘K’ in the device’s designation – CG0603MLA-26KE. The ‘K’ stands for Junction to center clamping voltage.

The CG0603MLA-26KE also features an enhanced safety structure that is designed to reduce the risk of long term damage to the application circuit. It is also designed with a negative temperature coefficient to maintain optimal operation under extreme temperature conditions, making it suitable for applications operating in high temperatures.

In summary, the CG0603MLA-26KE is the perfect choice for applications requiring protection from fast transient overvoltage events. It is a reliable and efficient device with a small footprint, high peak pulse current rating and enhanced safety structure. It is suitable for a wide variety of applications, including consumer electronics, telecoms, automotive, medical, and lighting equipment.
