V180ZA1PX2855

Varistors, also known as Voltage Dependent Resistors (VDRs), are components often used in circuit protection applications. They are a type of nonlinear resistor consisting of a sintered mass formed of semiconductor material. The resistance of a varistor depends on the voltage applied across it. If the voltage is below a certain threshold, the resistance of the varistor is infinite. Above the threshold, the resistance drops exponentially with increasing voltage.

The V180ZA1PX2855 is a surface mount varistor developed by Vishay. It has the smallest diameter of any available in the marketplace and is suitable for use in various applications. It features a high peak surge capability and excellent energy absorption rate.

The device is primarily used in the telecommunications industry for lightning and electrostatic discharge protection. It is also used in the automotive and industrial sectors for surge protection. It can be implemented in design to protect against over-voltage or over-current situations and also provide EMI/RFI filtering and immunity.

The V180ZA1PX2855 varistor works on the principle that when the voltage threshold is exceeded, the resistance of the varistor drops dramatically, creating a low-resistance path to ground for the surge or transient voltage. This prevents the voltage from reaching the sensitive components in the device. The V180ZA1PX2855 can handle spike voltages up to 270V and dissipates 7.5J of energy.

The V180ZA1PX2855 is available in a SOD-123 package with a lead pitch of 0.8mm. It has a resonance frequency of 4kHz and an operating temperature range of -55°C to 125°C. This device also provides a high long-term power handling capacity and low leakage current.

The V180ZA1PX2855 is an excellent choice for protecting sensitive components in telecommunications and industrial applications from over-voltage and over-current conditions. It features a high peak surge rating, low leakage current, and low resonance frequency. The small package size and high energy dissipation capabilities make it an ideal fit for compact designs.

The V180ZA1PX2855 provides enhanced safety protection for components and is designed for easy installation in high-density circuit boards. It is tested to meet the stringent requirements of various international protection standards and provides reliable transient protection from over-voltage and surges. This device is a great choice for providing circuit protection and is widely used in a variety of applications.
