TVS (Transient Voltage Suppressor) devices are components specifically designed to protect against electrical surges. MOVs (Metal Oxide Varistors) and Varistors are two of the most commonly used types of TVS devices. The 0072.4691.B1 is a surface-mount Varistor, exhibiting high reliability when used to provide protection from over-voltage transients, particularly in the telecommunications and automotive markets.

0072.4691.B1 is typically used in a parallel configuration with a voltage-limiting device, such as a fuse or a resistor. It is connected across the power lines of the device being protected, so that if a voltage spike or surge above the varistor’s clamping voltage, the device will conduct current away from the protected load. The advantage of this type of protection is that it can handle high-energy transients without damage to the device or disruption of the circuit, while also allowing for normal operation of the device.

The working principle of the 0072.4691.B1 is based on its internal diode array and electrodes. The Varistor is designed so that when the voltage across it increases, it begins to conduct, allowing current to flow through it. This current is diverted away from the protected device, thus limiting the current flowing through the circuit. The Varistor then acts like a circuit breaker, limiting the amount of current that can go through the protected load and preventing permanent damage to the device.

The 0072.4691.B1 is designed to have a clamping voltage of 24V, which is the maximum voltage it can handle before it starts to conduct current away from the protected device. Additionally, it has a maximum power rating of 1W, which means it can handle up to 1W of power before it needs to be replaced.

Because it is a surface-mount device, the 0072.4691.B1 is very easy to install on circuit boards. It can be soldered directly onto the board, so there is no need for additional components such as sockets or headers. This makes it ideal for applications where space is limited or where fast installation is important.

The 0072.4691.B1 is also designed to be RoHS compliant, meaning it is made from lead-free materials. This makes it safe for use in areas where lead-containing components are prohibited. In addition, the device is rated for operation over a temperature range of -55°C to 125°C, meaning it can be used in a wide variety of applications without worrying about it malfunctioning under extreme temperatures.

The 0072.4691.B1 Varistor is a reliable and robust device that is ideal for the protection of electronic systems from voltage transients. It is well-suited for applications in the telecommunications and automotive markets, as well as for many other applications where a cost-effective, easy-to-install, and RoHS compliant device with a broad temperature range is required.
