TVS (Transient Voltage Suppressors), MOVs (Metal Oxide Varistors) and V05P42AUTOs are all surge protectors that are used to safeguard electronic circuits from voltage transients and high voltage surges. They are passive devices, meaning no external power is required to operate them. All that is needed is a connection to the circuit they are protecting.

V05P42AUTO is a type of planar transient voltage suppressor designed to provide protection from transient voltage spikes. It is based on the MOV technology and utilizes a series of polysilicon bridges that are integrated onto a silicon substrate. This provides it with the advantage of having a smaller footprint and being more economical. The V05P42AUTO features a low capacitance of 2pF, making it suitable for use in high-speed data and communication applications.

The V05P42AUTO has a wide working voltage range between -3V to +60V with peak pulse current ratings ranging from 5A up to 30A. The working slew rate of the V05P42AUTO is 0.75V/ns, which makes it suitable for high-speed circuits.

The protective reaction time of the V05P42AUTO is 2.5 ns max. The overvoltage release time, which is the time it takes for the device to switch off in the event of an overvoltage, is 25 µs max. This is important for providing adequate protection from lightning strikes.

The V05P42AUTO has many applications in the automotive industry. It is utilized in a range of vehicles for protection against voltage transients and surges. The devices provide protection for entertainment systems, electrical control systems, instrument clusters, navigation systems, and control modules. The V05P42AUTO is also used in electric and hybrid vehicles to protect the high-voltage battery system.

The working principle of the V05P42AUTO is quite simple. The planar geometry of the device helps to protect against high voltage transients. The polysilicon bridges of the MOV work to absorb the excessive voltage generated by the surge while the internal drain of the device redirects the power safely away from the sensitive circuitry.

The V05P42AUTO is a reliable and economical solution for transient voltage surge protection. Its planar structure and low capacitance make it suitable for high-speed circuits and its overvoltage release time provides protection from lightning strikes. Thanks to its wide range of applications in the automotive industry, the V05P42AUTO is a useful tool for protecting sensitive electronic components from voltage transients and high voltage surges.
