V39ZA05PX2855

TVS (Transient Voltage Supressors) are an integral part of many electronics systems because they are capable of effectively suppressing fast – changing burst of voltage that can otherwise damage electronic components. Varistors, MOVs (Metal Oxide Varistors), and zener diodes are all types of TVS devices.

V39ZA05PX2855 is one type of TVS – Varistors and MOVs. This type of device is designed to provide a fast and reliable solution to protect electronic components against electrostatic discharge (ESD) and surge events. It is a simple device consisting of metal oxide compounds between two electrodes.

It features excellent electrical characteristics in both dynamic and static overvoltage conditions. The device can provide high surge current (Ipp) performance up to 25kA with low clamping voltage and self-resetting capability.

V39ZA05PX2855 is specifically designed to protect automotive systems from transient voltage, such as in vehicle battery and reverse power drain applications. It is also suitable for other high voltage applications, such as photovoltaic solar cells, power supplies, DC-DC converters, and automotive computers.

The working principle of V39ZA05PX2855 is relatively simple. When a surge voltage is applied to the device, the metal oxide compounds will be polarized and will start to release electrons. The released electrons will then be directed to the positive side of the device. The electrons will build up on the positive side, which creates a potential difference between the two electrodes as well as a current to flow which would then reduce the voltage of the surge.

V39ZA05PX2855 is specifically designed to provide a low clamping voltage behavior coupled with a low capacitance to protect I/O pins from ESD and surges. It provides a cost-effective alternative to conventional silicon avalanche diodes. The device has excellent surge current rating (Ipp) up to 25kA and has very low leakage current.

In conclusion, V39ZA05PX2855 is a TVS – Varistors and MOVS device specifically designed for automotive and high voltage applications. It features excellent electrical characteristics in both dynamic and static overvoltage conditions, with a high surge current performance (Ipp) up to 25kA. The working principle is relatively simple where the metal oxide compounds between two electrodes will be polarized and electrons will be released to create a potential difference between the two electrodes.
