TVS - Varistors, MOVs

The V14MLA0603H is a miniature radial lead transient voltage suppressor diode commonly used in electronic circuits for protection. This device can protect electronic components from the damage that can be caused by excessive voltage, such as electrical surges and electrostatic discharge. It works by reducing the applied voltage, ensuring that the voltage does not exceed the maximum allowed in the circuit.The V14MLA0603H is a varistor, which is a type of non-linear resistor that utilizes the voltage-current non-linear characteristic of a material to respond to an over-voltage. When a voltage is applied to the device, it acts as a very low resistance in one direction and a very high resistance in the other direction. This allows it to dissipate relatively large amounts of current when a voltage spike is present.The V14MLA0603H is also an MOV, or metal oxide varistor. This type of varistor is made from a ceramic material that is made up of zinc oxide and other metal oxides, such as molybdenum oxide. These metals have been mixed together in various ratios to create a material with a wide breakdown voltage and a wide bandwidth. This allows it to protect components from very low to very high voltage transients.The working principle of the V14MLA0603H is relatively straightforward. When a voltage spike is encountered by the device, it will start to conduct. This will cause it to act as a short circuit between its two electrodes, which will draw a large amount of current from the circuit and will help to reduce the voltage in the circuit. This current will then slowly decrease over time until it reaches its equilibrium point and the device can no longer conduct.The V14MLA0603H has various applications in the electronics industry. It is commonly used in power supplies to protect the components from overvoltage transients, as well as in logic circuits on printed circuit boards to protect the components from electrostatic discharge. It is also used in DC-DC converters, solar inverters, commercial appliance protection, automotive applications, and uninterruptible power supplies.In summary, the V14MLA0603H is a varistor and an MOV used in numerous electronic applications. It works by reducing the applied voltage, drawing a large amount of current from the circuit when an overvoltage is encountered. This helps protect the components from overvoltage transients and can help extend the life of the device.
