The TMOV34S681MPX2696 is a multi-function and multipurpose Metal Oxide Varistor (MOV) device, designed to protect circuits from high voltage transients and electrical surges. It is considered a key component in the effective protection of circuits due to its superior broadband transient performance. It is basically an overcurrent protection device that absorbs, quenches, and disperses potentially damaging electrical surges.

Although it is designed primarily as a transient voltage surge suppressor, the TMOV34S681MPX2696 can also be used as an absorption switch in high voltage circuits, and as a time delay circuit to protect equipment from damaging power line transients. It is also optimally suited for over current protection in medium to high-power applications. In short, the TMOV34S681MPX2696 can be used to protect a wide range of electronic components and systems from over-currents and power transients.

A typical application of the TMOV34S681MPX2696 is in motor controls and Solid State Relays (SSR). In these applications, it helps protect the circuit from large electrical surges that can cause noise and interference in the circuit. It is also used in high-voltage systems, such as electric power distribution systems, as well as in industrial process applications.

The TMOV34S681MPX2696 features a thermal fuse, which opens when the temperature of the varistor exceeds its rated temperature. This protects the circuit from thermal damage. The varistor also features a unique construction, which provides superior surge protection over conventional varistors. The construction is non-linear, and consists of zinc oxide particles embedded in a thermoplastic blend. This design offers improved surge handling capability, better thermal stability, and lower energy absorption than conventional MOVs.

The working principle of the TMOV34S681MPX2696 is similar to that of a conventional MOV. When an external overvoltage is applied, the MOV responds by increasing its resistance, thereby absorbing and dispersing the surge. The device has a fast response time of less than 60ns, which helps to reduce any possible inrush current that may be generated during a voltage surge. This fast response time also helps to minimize the amount of energy absorbed, and increases the effectiveness of surge protection. The device is also designed to minimize electro-magnetic interference, by minimizing the rate of current change.

The TMOV34S681MPX2696 is a very versatile device, and is suitable for use in a wide range of applications, such as overvoltage protection in lightning protection systems, overvoltage protection in energy supply systems, and for EMI suppression. It is highly dependable, and its outstanding surge handling performance makes it a reliable choice for engineers and technicians. It is also very easy to integrate into existing circuits, making it an ideal solution for existing and new installations.
