V82ZA20PX10 Circuit Protection

TVS (Transient Voltage Suppressor) devices, including varistors, MOVs (Metal-Oxide Varistors) and other types, are widely used to protect sensitive electronic components from overvoltage events caused by ESD (electrostatic discharge), lightning strikes, and other transient events. The V82ZA20PX10 is a general-purpose TVS device designed to protect electronic circuits against overvoltage transients and ESD when properly installed. It is a bidirectional device and combines the positive characteristics of a zener diode with the fast response of a varistor.

The device is packaged in a SMD (Surface Mount Device) case and encapsulated with an epoxy coating. It features two terminals which are connected via a flat-bed silicon wafer. The silicon wafer is mounted to a metal base, which serves as the ground connection. A metal plate is then connected to the silicon wafer to form the positive connection. The design ensures that the device can withstand up to a 20 Volt transient voltage.

When exposed to a transient over-voltage, the device’s metal oxide layers break down and become conductive, absorbing the energy of the transient and dissipating it safely. This allows the device to effectively protect the components in the circuit from over-voltage transients. The V82ZA20PX10 is designed to work in a temperature range of -55°C to 125°C, and has an endurance rating of 10 V/μs.

The electrical parameters stated by the manufacturer for the V82ZA20PX10 device are: Peak Pulse Power, Ppp (W), Breakdown Voltage, Vbr (V), and Peak Pulse Current, Ipp (A). The Peak Pulse Power determines the amount of energy the device can absorb when exposed to an over-voltage transient. The Peak Pulse Current is the maximum current that the device can handle before becoming damaged. The breakdown voltage is the point at which the device becomes conductive and starts diverting the current away from the circuit.

The V82ZA20PX10 is ideal for a wide range of applications, including automotive, industrial control, data and signal transmission, and consumer electronics. It can be used in a wide range of circuit protection applications involving high-speed transients and ESD protection, including ESD protection for charge pumps, DC-DC converters, RS232 and LVDS circuits, and audio systems. The device is also widely used in a variety of consumer electronics, such as digital cameras, cell phones, and video game consoles.

In summary, the V82ZA20PX10 is a versatile and reliable TVS device designed to provide effective overvoltage transient and ESD protection for a wide range of applications. Its bidirectional design, low capacitance, and fast response make it an ideal choice for many circuit protection applications.
