TVS - Varistors, MOVs are devices that protect vulnerable electronic equipment from potentially damaging transients. A Transient Voltage Suppressor (TVS) or a Metal Oxide Varistor (MOV) is a device that limits transient voltages and current spikes through the use of a capacitor, thus protecting sensitive electronic equipment from electrical surges.

The TMOV34S181MX2696 is a metal oxide varistor with an 8-pad, 3 x 4mm package size. It is designed specifically to provide surge over-voltage protection, with an operating voltage range from 0-18 volts. It features robust construction, a wide operating temperature range, and a varistor element that is fully encased and protected from physical and electrical damage.

The TMOV34S181MX2696\'s surge current handling capability is 5.5A (pk), i.e., it can withstand a transient surge current up to 5.5A without damage. It is designed for operation over an ambient temperature range of -40C to +85C, and is qualified to AEC-Q200 standards. In addition, it is RoHS compliant, and is UL recognized.

The TMOV34S181MX2696 can be used in a wide range of applications, such as automotive, industrial, communications, consumer electronics, computers and peripherals, power supplies, and many more. Its primary function is to protect sensitive circuits from transient voltage and current fluctuations that can be caused by lightning strikes, power-line surges, electrostatic discharges, or electromagnetic interference (EMI). The TMOV34S181MX2696 can also be used as a general-purpose surge protection component within a circuit.

The working principle of the TMOV34S181MX2696 is based on the principle of the Metal-Oxide Varistor (MOV). A MOV is composed of a metal oxide material that, when exposed to a voltage beyond its breakdown rating, exhibits a non-linear resistance. This non-linear resistance limits the current and/or voltage to the corresponding characteristic of the MOV. As the voltage returns to its normal level, the resistance of the MOV returns to its prior level.

In the case of the TMOV34S181MX2696, its nominal break-over voltage is 18V, and it has a capacitance of 500pF. When exposed to a voltage spike above 18V, an increased current flows through the MOV, which limits the voltage to the break-over voltage (18V). At the same time, the MOV\'s capacitance ensures that any transient current is dissipated as quickly as possible. This ensures that the device does not become damaged by the transient and protects the load from damage.

In conclusion, the TMOV34S181MX2696 is an ideal choice for surge protection in a variety of applications. Its robust construction and wide operating temperature range make it suitable for a range of applications. Its Metal Oxide Varistor working principle provides a reliable and effective means of suppressing potentially damaging transient voltages and current spikes.
