Varistors, also called voltage dependent resistors (VDRs), are a special class of semiconductor technology that have a very high resistance as a function of voltage. The V480LS80BPX10 is a metal oxide varistor device designed specifically to protect sensitive electronic devices and sensitive circuitry from transient voltage spikes. It is characterized by a low leakage current (less than 0.1uA at 1mA) and a low capacitance (<0.1pF) typical for metal oxide varistors.

V480LS80BPX10 Application Field and Working Principle

The V480LS80BPX10 has a wide range of applications including motor control, industrial automation, and even consumer electronics. It can be used as a surge protector, clamping device, voltage stabilizer, or transient voltage suppressor in these and other applications. It provides protection from over-voltage/under-voltage and prevents permanent damage to the connected device or circuit by dissipating the load without damage or destruction.

The V480LS80BPX10 works on the principle of silicon avalanche breakdown. It works by clamping the input voltage and allowing the excess voltage to be dissipated through the varistor. The varistor has a rated voltage that corresponds to the maximum voltage it can clamp. When subjected to above this voltage, the internal structure of the varistor will break down, allowing the excess voltage to flow from an anode to a cathode, where it is dissipated as heat in the device.

V480LS80BPX10 boasts an excellent Flame-Retardant-Type enclosure with an epoxy molding compound which conforms to UL 94V-0 standard, rated for UL 94V-0 for 10 seconds at 1040°C, certified RoHS compliant, and is available in both in 0805 package sizes. It also has high surge current and ESD capability, using a thermoplastic base casing, with a surge current protection of up to 10,000A (8/20μs). It also has excellent temperature coefficients, which allows for a wide temperature range of operation up to 125°C.

V480LS80BPX10 metal oxide varistors possess a high energy absorption capability, excellent non-linear voltage-current characteristics, and high surge capability. This makes them suitable for use in a variety of applications. When used as an over-voltage protection device, it can regulate the excess voltage generated by inductive loads, such as transformers, and other transient disturbances.

The V480LS80BPX10 can also be used as an ESD protection device, protecting equipment such as PCs, video devices, or other electronic equipment, as it can absorb high voltage surges. It can also be used with touchscreens, to protect from static voltage build-up due to human body contact, and to provide a smooth operation regardless of the user’s interaction with the touchscreen.

The V480LS80BPX10 is also an ideal transient voltage suppressor, as it can absorb high energy surge transients and provide protection to a variety of sensitive electronic systems, such as satellite and other communication equipment, ATM machines, and power supplies.

Finally, the V480LS80BPX10 is a great device for use in motor control applications, where it can provide protection from high current load transients. This is due to its low clamping voltage and high surge capability, and excellent temperature coefficient.

The V480LS80BPX10 is an ideal solution for various transient voltage applications, as its high energy absorption, low leakage current, low capacitance, and high surge capability make it suitable for a wide range of applications. It is RoHS compliant and offers excellent flame-retardant capabilities, making it both safe and reliable. Additionally, its 0805 package size offers a great balance between size and power, making it an ideal solution for a variety of applications.
