V275SM7 Circuit Protection

TVS - Varistors, MOVs, are electrical components used for the protection of electronics from transient overvoltage events. The V275SM7 is a device specifically designed to protect automotive electronics devices from transient voltage surges and electrical noise.

This component is a multilayer ceramic varistor with a 275 volt maximum clamping voltage, making it suitable for use within 12 volt automotive systems. The maximum operating temperature is 125°C, allowing it to operate in harsh automotive environments. In the case of an over voltage, it can take in up to 6000 volts while providing discharge paths for any transients that breach the 275 volt limit.

The V275SM7 is a non-linear resistive device which operates by varying its resistance based on the voltage applied to its terminals. When a transient voltage spike occurs, the resistance of varistor decreases significantly, thereby allowing the passage of a high surge current phenomenon. As this process takes place, the total energy of the transient is absorbed by the V275SM7, acting as a direct power dissipation element.

The V275SM7 is ideal for use in a wide range of automotive applications such as safety systems, fuel injection systems, lighting and audio systems, and charging systems. In addition to providing protection for automotive electronics, it can also be used to protect consumer electronics such as mobile devices, computers, and televisions.

Using a multilayer ceramic structure, the V275SM7 offers up to 275 volts of electrical noise suppression and is capable of handling up to 220 nanoamps (VN: \muA) of steady-state current. This makes it well suited for automotive electronics applications, where it is important to ensure that any electrical noise or spikes are effectively attenuated to ensure proper functioning of the device.

The V275SM7 is produced in a wide variety of form-factors, including a wide variety of surface-mount packages such as SOT-23, SC-74, SOT-223, and more. It also offers a choice of lead-free, halogen, and standard versions allowing for use in a wide range of applications with different environmental standards.

In summary, the V275SM7 is a multilayer ceramic varistor specifically designed for the protection of automotive electronics from transient overvoltage events. It offers a maximum clamping voltage of 275 volts and a maximum operating temperature of 125°C, and is available in a variety of form-factors for use in a wide range of automotive applications.
