Transient Voltage Suppressor (TVS) devices, such as Metal Oxide Varistors (MOVs) and V420LS20CPX2855, are a type of electronic components used to protect circuits from voltage spikes. MOVs are used to protect AC power lines from transient events, while V420LS20CPX2855 are designed to protect low voltage DC circuits.

V420LS20CPX2855 are commonly used in automobile, machine tool, computer, consumer electronics and communications industries due to their small size and low cost. V420LS20CPX2855 offers good performance in various automotive applications such as ESD, surge protection, reverse polarity protection, and noise suppression.

The working principle of V420LS20CPX2855 is based on its nonlinear current-voltage (I-V) characteristics. It responds to transient surge voltages by clamping the voltage to a predetermined level, allowing a maximum current flow. The device has a zero voltage turn-on characteristic, allowing it to clamp only when the maximum surge voltage is exceeded. As the voltage drops, the device turns off automatically.

V420LS20CPX2855 is available in multiple package styles such as DIPs, SMDs and TO-220 devices. Its SMD version utilizes solid dielectrics such as polyester for enhanced surge protection, while its TO-220 version uses liquid epoxy to provide better stress relief.

V420LS20CPX2855 also has the capability to detect and respond to over-voltage conditions faster than other devices. This is due to its finely tuned active clamping circuit, which is optimized to provide maximum response time. Its active clamping circuit includes an avalanche diode, which allows the device to mount across the power line. This feature eliminates the need to install additional protection circuits in the system.

The V420LS20CPX2855 also utilizes an advanced surface mount technology called MicroFuseTM, which is used to bond the device\'s metal oxide layer to the metal contacts providing superior ESD and surge suppression performance. This surface mount technology also offers a high level of resistance to vibration and shock.

The V420LS20CPX2855 is a very reliable and robust device, making it ideal for use in automotive, consumer electronics, computers and other electronic applications. Its active clamping feature offers faster response time than other devices, while its surface mount technology offers superior ESD and surge protection. Its small size and low cost make it an attractive choice for many applications.
