TVS (Transient Voltage Suppressors) - Varistors, MOVs are varieties of voltage protection components that provide device-level protection in integrated circuits. These components provide a selective path to ground, allowing the circuit’s integrity to remain intact while dissipating excessive voltage.

The V47ZA05PX2855 is a type of voltage protection component from this series that is mainly used in computer, communication and consumer electronics. It basically functions as a circuit breaker, which is triggered when the voltage exceeds the set threshold.

Applied across a printed circuit board, the V47ZA05PX2855 has thermal protection that can be adjusted according to the operating environment. It provides fast circuit protection through a combination of TVS clamp diodes and MOSFETs. This component is controllable through an external resistor that is used to set the turn–on voltage. This feature allows for an accurate response to the surrounding environment and protects the system from inadvertent power supply failures.

In terms of construction, the V47ZA05PX2855 consists of an integrated circuitry which includes a PTC (positive temperature coefficient) resistor, TVS diodes, and MOSFET gates. The device also features a board current limiting element which helps to protect against dynamic voltage, allowing the system to stay protected in the event of sudden voltage changes. This current limiting element ensures that the internal components are not subject to long-lasting over-voltages. The resistor and the TVS diodes together offer a series of protection against transient voltage.

When it comes to the working principle, the PTC element helps in controlling the flow of current into the circuit. When an overvoltage condition occurs, the device trips a latch, and the MOSFET gates will eventually open allowing the current to pass through the diodes. The PTC element then triggers the latch, which opens the gate and effectively shunts the over-voltage away from the remaining components.

The device is also capable of self-recovery due to its trip-and-hold characteristics. It can withstand multiple overvoltage incidents without the need for a reset. Additionally, the device provides reverse polarity protection, short-circuit protection, and over-current protection.

The V47ZA05PX2855 is an ideal voltage protection component for use in many electronic products such as TV sets, computers, communication lines, household appliances, and digital terminals. With its efficient working principle and protective features, it is able to effectively protect circuitry in these devices from any type of overvoltage damage.

Overall, the V47ZA05PX2855 is a reliable and cost-effective voltage protection device that can be used in a variety of applications. Its easy installation and adjustable parameters also make it suitable for use on many kinds of electronic systems.
