0070.5081.A2

TVS - Varistors, MOVs

The 0070.5081.A2 device is a varistor, also known as a voltage-dependent resistor (VDR). It is an electronic component commonly used in many different types of applications. A varistor is a special type of resistor whose resistance changes with the applied voltage. The resistance of a varistor is usually very low at low voltage levels, but quickly jumps to its maximum value when the applied voltage reaches a predetermined threshold. This makes them ideal for protecting sensitive circuits from excessive voltage levels.

The 0070.5081.A2 is designed for use in applications where surges of high voltage must be reliably contained in order to protect other components. These surges could be caused by lightning strikes, power line surges, or other transient events. The component works by limiting the voltage to a predetermined threshold level. For example, if a user provides 12V to the device, it will remain at this voltage level until the voltage level goes above the maximum threshold. At this point, the device will switch on and start to conduct current, limiting the voltage and protecting the nearby components. Once the voltage level dips below the threshold, the device stops conducting and the connected components are protected.

The 0070.5081.A2 is a particular type of varistor commonly known as a Metal Oxide Varistor (MOV). It is made of several variable layers, each consisting of metal oxide semiconductors. The layers are connected in series, with the semiconductor material offering improved protection from transients by conducting current away from the protected circuit. The device also has a positive temperature coefficient (PTC), which means that as the temperature increases, the resistance of the MOV increases.

In addition to surge protection, MOVs are also used for line filtering and clamping. Line filtering can help reduce line noise that affects the performance of digital circuits. Clamping reduces the voltage swings that can damage circuit components. The 0070.5081.A2 has an attractive clamping voltage of 17 V, making it suitable for use in applications that require protection from over-voltage events.

Overall, the 0070.5081.A2 is an effective electronic component when it comes to providing surge protection, line filtering, and clamping. Its unique design offers excellent performance and reliability, making it ideal for use in many different types of applications. With its low clamping voltage and positive temperature coefficient, the 0070.5081.A2 is an excellent choice for those looking for reliable surge protection.
