The MLVA06V26C100 is an adjustable Voltage Dependent Resistor (VDR) device categorized under Transient Voltage Suppressors (TVS) - Varistors, MOVs. Varistors prevent voltage surges from damaging devices. By controlling the onset and clamp voltages of the surge, it provides an additional level of protection for delicate electronic circuit components.

Varistors composed of several layers of different semiconductors are all designed to safeguard electronic circuits from high-voltage transients and form a critical part of the power supply circuit. This type of component utilizes what is known as the Varistor effect, in which the resistance of the device changes namely reducing as the voltage increases, and then increasing as the voltage reaches a certain level at its peak. This effect is utilized in various types of Electronic circuits, like motor control circuits, automotive circuits, high power DC power supplies, etc.

The MLVA06V26C100 from is an adjustable TVS with good voltage dependence characteristic. It is highly configurable and depends on the user. Its clamp voltage can be adjusted to up to 100V. Generally, it’s recommended to use the MLVA06V26C100 when the supply voltage is above 60V.But 50V can also be used if the MLVA06V26C100 is combined with other suitable components. This makes this adjustable VDR component suitable for usage in switch-mode power supplies, computer monitors, telecom systems, and other high-end products.

In terms of its working principle, the device is designed with a Zener diode that regulates the voltage. It then limits the current flow when an over-voltage occurs. As this occurs, the charge controlling the current will move into what’s known as the leaky capacitors. The current is then dissipated through the capacitor\'s resister, thus preventing it from passing through the circuit and damaging the device.

The MLVA06V26C100 provides voltage dependent resistance from 4KΩ to 20KΩ across the range of operating currents. It is sensitive to overvoltage incidents and can quickly sense voltage in the surge range of 70V to 130V with a response time of 0.5ms with an overshoot voltage of 1.2 times more. This makes it ideal for ensuring that surges do not cause any permanent damage to an expensive or delicate electronic circuit.

In conclusion, the MLVA06V26C100 is a very important part of any circuit that employs switch-mode power or other forms of power supply and can protect a circuit from overvoltage surges. The adjustable clamp voltage of the device means it can be used in a different array of electronic circuits, allowing it to be an incredibly versatile component.
