Transient Voltage Suppressors (TVSs) are a type of finite voltage protection devices that are used to protect sensitive electronic components from electrical transients. They are typically connected between a signal and ground, and are designed to conduct excess current beyond normal operating conditions away from the protected components. TVSs are commonly used in labs, industrial applications, and consumer electronics.

Varistors and Metal Oxide Varistors (MOVs) are two of the most commonly used TVSs for transient voltage protection. Both types work by providing a finite path for current flow during an electrical overvoltage event. Varistors are mainly designed with a varistor element that is protected by a sacrificial component that will pass the excess current away from the protected components at a specified voltage. MOVs on the other hand are composed of multiple layers of metal oxide that conduct current away from the protected component at a specific voltage.

V2AF105A150Y2EDP is a Type 2+2 Surge Protective Device (SPD) manufactured by Semtech Corp. Its maximum continuous operating voltage rating is 150Vac. This SPD is composed of two parallel-connected Varistors and two MOVs in a single package, for both common mode and differential mode transient voltage suppression. It is designed for use in applications where high surge withstand capability is required.

The varistor element of the device is activated by an external force which causes the junction to start conducting current at the set overvoltage level. When the event passes, the varistor element recovers and the circuit returns to its OFF state. This feature allows the V2AF105A150Y2EDP to clamp high voltage transients at or below its threshold. The MOV element works by conducting current away from the protected components when an overvoltage event occurs.

The V2AF105A150Y2EDP is most suitable for applications that require both common mode and differential mode protection, such as electronic control systems, digital communication systems, cables, and communication systems. Its compact size makes it perfect for use in tight spaces, and its low leakage current and high clamping voltage make it an ideal choice for sensitive electronic components.

In summary, the V2AF105A150Y2EDP is a Type 2+2 SPD that is composed of two parallel-connected Varistors and two MOVs in a single package. It is designed for use in applications where high surge withstand capability is required, and provides both common mode and differential mode transient voltage suppression. Its compact size and low leakage current make it an ideal choice for tight spaces and sensitive electronic components.
