TVS (Transient Voltage Suppression) devices, the acronym itself suggests the sole purpose and intention of its use, is a choke which is used to regulate high voltage, which can otherwise harm the electronics. Varistors, one of the largest product category of this type of technology protects against surges and accidental contact with high voltage. MOVs (Metal Oxide Varistors) are static overvoltage suppressors that absorb surges and spikes in power by gradually diverting it to ground should it exceed a predetermined threshold.

CN0603K25G is a TVS – Varistor – MOV device which works based on the principle that a certain amount of voltage will cause it to start dissipating power, or in other words, reduce the sudden jump in voltage or current and divert it to the ground. It’s a two-terminal, bidirectional device which is fabricated entirely by high temperature surface mount technology. This device features a capacitance value of 10-25 pF and a voltage rating of 16V.

The applications of CN0603K25G device are essentially restricted to low voltage environments and transition control for data and signals in modern digital/analog applications. This device is a unidirectional device designed to protect against high voltage attempts. It is widely used for transient voltage protection of sensitive electronics such as integrated circuits, lasers, or consumer electronics. CN0603K25G device is also popularly used where devices are subjected to one-way shocks from power surges or close proximity with high voltage lines.

The working principle behind the CN0603K25G device is based on the fact that it contains charge carriers which move between the free electrons and positively charged movable ions. Its high internal resistance is crucial which permits it to store higher voltage and energy. Under normal or recreational conditions, its right ions remain in the place, leaving the circuit active. However, upon high voltage arrival, these right ions start to wander from their existing places and join their free electron counterparts, thus momentarily raising resistance and hence breaking the path for the current.

In conclusion, CN0603K25G is a highly efficient, cost effective and reliable device which always remains active and can be used in many digital/analog applications to protect against high voltage. This MOV device can be easily integrated into any system and also offers reactivation with no longterm damage or performance loss, thanks to its superior thermal design.
