Transient Voltage Suppressors (TVS) devices such as Varistors, Metal Oxide Varistors (MOVs) and TransZorbs have become increasingly popular with advances in technology to protect circuits from heavy surges and EMI (electromagnetic interference) disturbances.

The V82ZA2PX2855 is a metal oxide varistor (MOV) specifically designed for applications that require higher surge protection capabilities, such as communications systems and power systems. It is particularly suitable for use in telecom and distributed power network equipment, LED lighting systems, and other high-end applications.

The V82ZA2PX2855 has a clamping voltage of 48V, and its clamping voltage is 20-25% higher than that of other TVS devices. Its superior peak pulse pulse current performance allows it to withstand very large transient surges, making it ideal for applications such as telecom cable, distributed power networks, and LED lighting systems which can be exposed to large transient surge events. It is also capable of handling up to 75A (10/1000us waveform).

The V82ZA2PX2855 is constructed in a TO-220 format and is available with a voltage rating of up to 62V. The device measures 8.0 X 12.0mm and has a wide -55 to 150℃ operating temperature range. It has a maximum peak pulse pulse current rating of 75A, and a maximum peak forward surge current rating of 36A.

The V82ZA2PX2855 is designed to suppress high voltage transients by clamping their voltage to a safe level. This is accomplished by utilizing the intrinsic capacitance between the gate-to-body and gate-to-drain terminals between the MOV and the transistor. This capability is the result of the low clamping voltage of the MOV, which allows it to be safely connected to a sensitive component such as a transistor with low output resistance. In addition, the MOV provides high levels of EMI protection by absorbing high frequency noise.

The V82ZA2PX2855 is also designed to reduce stress on surrounding components and reduce the chances of fire due to overload. It does this by vaporizing a portion of the MOV\'s structure at the time of the transient, thus preserving the integrity of the surrounding components. The device also provides over-temperature protection, preventing the overheating of the MOV that can lead to fire.

The V82ZA2PX2855 is a cost effective and reliable solution for applications that require protection from heavy surges and electromagnetic interference disturbances. It is designed to protect sensitive components and reduce the chances of damage due to overload. Its wide temperature range and high peak-pulse pulse current rating make it suitable for a variety of applications, including telecom, distributed power networks, and LED lighting systems.
