TV30C100J-G is a component that belongs to the category of TVS - diodes. It serves as a direct current (DC) voltage clamp, absorbing voltage spikes that may occur on power supply lines. TV30C100J-G helps ensure electrical protection for PCBs and other electronic equipment in general. It can be used to protect such equipment from current surges and lightning strikes.

A TVS device is basically composed of Zener diodes and Metal Oxide Varistor (MOV). The MOV consists of a die-cast pellet formed in Compositions of Material (COMs). It is located between two electrodes and shows nonlinear behavior breakdown voltage, based on the increasing voltage and the decreasing resistance values, after reaching the breakdown point.

When subjected to a voltage spike, TV30C100J-G acts immediately. The current flows through the diode’s Zener junction. Through the applied voltage, the junction begins to breakdown and the current then shifts to the MOV resistor that acts as a shunt. As the MOV\'s voltage and resistance begin to drop, TV30C100J-G redirects the excess current into the ground, thus protecting the other components.

The other most common type of TVS is a multi-layer varistor (MLV). MLVs are known for their low voltage rise, low power consumption and high current surge ratings. They are easily mounted on the PCB via either a surface mount or through-hole method. MLVs are particularly suited for applications where large amounts of power are required such as Personal Computers (PCs), servers, switches, and other mission-critical components.

When compared to regular metal oxide varistor (MOV) diodes, MLVs offer a longer lifespan in repetitive surges, improved thermal performance, and greater transient suppression. It is possible to achieve power ratings up to more than 25 Watts in a single part using MLVs.

TV30C100J-G is a particularly reliable and efficient type of MLV. It has both low and high voltage ratings. The thin-film flat chip construction of TV30C100J-G also allows it to offer superior electrical and thermal parameters. The chip also possesses a high current carrying capability with an impressive temperature coefficient. This means that even when exposed to high temperature, the device still remains reliable.

The working principle of TV30C100J-G is simple. When a voltage­ spike occurs, the chip absorbs the excess voltage, allowing current to flow through Zener and MOV junctions. The excess current is then diverted to the ground where it can be safely discharged. In this way, the chip absorbs the excess voltage, thus protecting the other components from surges and shocks.

TV30C100J-G has vast applications in commercial and industrial systems. It can be used for power supplies and other components that require protection from ESD, EFT, lightning, and surges. It is commonly used for the protection of telecom and network devices, industrial and medical equipment, consumer electronics, and automotive systems.

All in all, TV30C100J-G is an extremely efficient and reliable type of TVS device. Its thin-film flat chip construction makes it easy to mount on PCBs, while its superior electrical and thermal parameters provide excellent protection from current surges and voltage spikes.
