TVS - Varistors, MOVsThe V20E385PL1T is a varistor, also known as a voltage-dependent resistor (VDR), that is used in many types of electronic circuit protection applications. It is particularly well suited for guarding against overvoltage and transients. Varistors are devices that are used to protect electronic circuits from surges such as electrostatic discharges, lightning strikes, and high inrush currents.Varistors are composed of two types of material: a metal oxide semiconductor (MOS) and a ceramic core. The MOS layer is made up of zinc oxide, aluminum oxide, or other types of metal oxides. The ceramic core is usually made of a polycrystalline material such as alumina or zirconia. The MOS and ceramic layers are then laminated and encapsulated in an epoxy shell for protection.When used in a circuit, the V20E385PL1T varistor acts as a voltage-dependent resistor. That is, when the voltage across its terminals is below a certain threshold, the varistor will have very little resistance. However, when the voltage across its terminals exceeds this threshold, the varistor’s resistance will rapidly increase. This property makes it ideal for suppressing transient voltages and surges, since it limits the amount of current that can flow through the circuit.The V20E385PL1T is commonly used in AC power lines, DC power supplies, and audio and video circuits. In AC power lines, it provides protection from voltage spikes caused by lightning strikes and power outages. In DC power supplies, it serves to protect sensitive components from current transients and voltage surges. In audio and video circuits, it guards against distortion caused by static electricity and signal transients.Due to its high current-handling capabilities and rugged design, the V20E385PL1T is also often used in industrial and automotive applications. In industrial applications, it can be used in motor control circuits, elevator systems, and other equipment containing potentially dangerous voltage spikes. In automotive systems, it is often used in alternators, fuel injectors, and other automotive systems where voltage spikes can cause damage.The V20E385PL1T has many features and advantages that make it ideal for a variety of protection applications. It has a wide operating temperature range of -40°C to 85°C and a high-clamping voltage of 20V. Additionally, it is capable of handling up to 1.7A of surge current, making it suitable for a wide range of microcontroller and FPGA applications. It also has a high surge life rating of 20,000 surge cycles, meaning it can provide reliable protection against transient voltages and surges over an extended period of time.Overall, the V20E385PL1T is a versatile and reliable voltage-dependent resistor that can be used in a variety of circuit protection applications. Its wide operating temperature range, high-clamping voltage, high surge current-handling capabilities, and long surge life rating make it an ideal solution for protecting sensitive components from voltage transients and surges. Additionally, its rugged design and wide availability make it appropriate for use in a variety of industrial and automotive applications.
