V480LU80BPX10 Application field and Working Principle

TVS (transverse voltage suppressor) is an electrical protection device that is designed to protect vulnerable components from intermittent overvoltage conditions. TVS devices, also known as transient voltage suppressors, can protect against overvoltage transients such as electrostatic discharge (ESD). TVS are available in many different technologies, such as MOVs (metal oxide varistors), Zener diodes, Silicon avalanche diodes, and diac semiconductor devices. The V480LU80BPX10 is a TVS device from Diodes Incorporated that is part of the SuperSOT-5 product family. It is an MOV (metal oxide varistor) and is designed to protect against both ESD and lightning-induced transients.

Overview of the V480LU80BPX10

The V480LU80BPX10 is a 12.5V, 1-line bidirectional device that is designed to protect sensitive ICs from electrostatic discharges up to 30A (8/20μs). The device is rated for a peak pulse power of 1.92 W and a maximum clamping voltage of 28.5V.

The device is packaged in a small and compact 3-pin SOT-23 form factor that allows for a minimized PCB footprint. The V480LU80BPX10 is designed to meet numerous industry standards such as IEC60747-5-2 and IEC61000-4-2, and it is compliant to the requirements of the RoHS Directive.

Operation of the V480LU80BPX10

The V480LU80BPX10 is an MOV device, which means that it consists of a metal oxide varistor element. The element is composed of a zinc oxide crystal and two metal plates. The device works by clamping overvoltage transients, and the MOV element is responsible for this function.

When the device is subjected to an overvoltage transient, it acts as a parallel resistor to the existing circuit path. This causes a voltage drop, which reduces the peak voltage of the transient. At the same time, current will be diverted away from the circuit and into the device. This prevents the transient voltage from damaging the sensitive component and keeps the device within its normal operating voltage range.

The V480LU80BPX10 is designed to work in a wide variety of applications such as telecom, consumer electronics, computing, and automotive industries. It is well suited for protection of I/O ports, data lines, bus lines, and phone lines. It is also used in high-speed communication lines, such as USB.

Conclusion

The V480LU80BPX10 is a versatile and highly reliable TVS (transient voltage suppressor) device that can provide protection against electrostatic discharge (ESD) and lightning-induced transients. It is composed of a metal oxide varistor element that clamps overvoltage transients and diverts current away from the circuit. The device is packaged in a small 3-pin SOT-23 form factor and is compliant to the requirements of the RoHS Directive. It is suitable for a wide range of applications, such as telecom, consumer electronics, computing, automotive, and high-speed communication lines.
