TVSs (Transient Voltage Suppressors) are unidirectional devices that provide enhanced protection on signal or power lines from transients caused by lightning, electrostatic discharge, electromagnetic interference (EMI) or other voltage surge events. Varistors, MOVs (Metal Oxide Varistors) and Polymeric Positive Temperature Coefficients (PPTCs) are components in the TVS family.

V130LU10CPX2855 is a bidirectional overvoltage protector that functions as a differential voltage clamp with excellent transient protection characteristics. It can provide differential bi-directional protection up to 8V peak with maximum clamping voltage of 14.5V, allowing for a wide operating range between -10V and +28V. The device enables a current handling capability up to 5A, with low capacitance of 1.6pF typical at the I/O.

The V130LU10CPX2855 application fields include power and signal systems found in consumer electronics, automotive, industrial, and LED lighting. It is commonly used to protect automotive electronics such as infotainment, gateway and telematics systems, smart grid systems, USB Type-C E-Fuse, AC and DC LED lighting circuits. The device is also used as a general-purpose high performance diode/MOSFET/IC protection component.

The working principle of the V130LU10CPX2855 is based on a positive temperature coefficient diode connected in series, which limits the surge current to safe level. The main advantage of positive temperature coefficient devices is that, under normal operating conditions, they present no conduction path between the power and the ground. However, when the voltage level is above a certain level, the temperature of the diode increases, which reduces its control voltage and causes the diode to conduct. This limits the voltage and current to a pre-set level determined by the design of the device.

In addition, the V130LU10CPX2855 device also features an integral PTC (Positive Temperature Coefficient) that helps to reduce overvoltage events by absorbing and dissipating surge current. The PTC is normally in a high resistance state and starts to conduct current when the current exceeds a specific threshold, allowing it to act as an overcurrent or short circuit protector.

The V130LU10CPX2855 provides superior protection performance, boasting low clamping voltage, low capacitance, excellent response times, and strong protective features. It is an ideal device for system designers who require reliable high performance surge protection for applications with wide operating ranges.
