TVS - Varistors, MOVs are widely used for protecting circuits or equipment from static voltages and transients in electronic circuits. The V0603MHS12NA is a S0603 (2.1mm×1.6mm) surface mounted device voltage suppressor from Vishay. It is a monolithic sand-tailed type varistor product designed to protect circuits from ESD, EFT, inductive cross-talk, lightning and other transient voltages.

The V0603MHS12NA application field includes automotive, medical, consumer, telecommunication, industrial control, home appliance, process control, aerospace, and military. Due to its capability of providing a low clamping voltage, minimum power dissipation, and fast transient response, the V0603MHS12NA can be used in various types of equipment. For example, it is used in electric vehicles, control systems, main drive circuits, UPS systems, computers, and communication electronic circuits.

The construction of V0603MHS12NA is based on a Metal Oxygen Silicon (MOS) varistor. The varistor is a two-terminal, non-linear, and non-polarized semiconductor device. It is built by depositing semiconductor material on two electrodes, which creates a capacitor-type of connection with one capacitor connected in parallel with another. The V0603MHS12NA is designed to have the proper clamping ratio to offer overvoltage protection from transient (surges/spikes) voltages. The element itself is essentially a part of a voltage divider with the varistor having a higher resistance than normal resistance. This creates the disparity in the total resistance, which allows the varistor to start conducting when a certain voltage level is reached.

The working principle of V0603MHS12NA is based on the varistor effect. When a voltage is applied to the element, the V0603MHS12NA will have a much lower resistance than it appears on the data sheet (typically a few ohms). The varistor effect occurs when charge carriers jump across the varistor junction, adding a very large reverse current to the circuit when necessary. This occurs until the applied voltage exceeds the varistor\'s nominal voltage (also called the breakdown voltage) and it then reduces its resistance to provide over-voltage protection.

The V0603MHS12NA from Vishay is designed to provide reliable protection of automotive, medical, consumer, telecommunication, industrial control, home appliance, process control, aerospace, and military equipment against over-voltage transients. It uses the varistor effect, offering a low clamping voltage with minimum power dissipation. This varistor is a reliable overvoltage protection solution, which is used in many applications due to its excellent performance.
