The TVS- Varistors, MOVs, is an important component in voltage protection applications. The V39ZS1PX2855 is specifically designed to provide reliable protection for low voltage and low power applications. This device offers a unique combination of low capacitance, low leakage current, and good transient response, all while having a relatively small package size.

The V39ZS1PX2855 is an ultra-low capacitance, low power, transient protection diode. The device is composed of a series of two p-n junctions configured as gamma diodes, which provide a voltage dependent behavior. This structure provides a fast, reliable, low capacitance, low-power protection over a wide voltage range.

The main application field of V39ZS1PX2855 includes low voltage power supplies, switch mode power supplies, DC-DC converters, uninterruptible power supply, data-acquire systems, portable electronic devices, USB port protection, and Ethernet protection. In the whole application field, the device is capable of providing protection for power converters, interfaces, and input/output signals.

The working principle of V39ZS1PX2855 is based on the avalanche breakdown phenomenon. The device is composed of two series-connected semiconductor junctions, arranged in the form of a gamma diode. When the voltage applied across these two junctions exceeds the breakdown voltage, current rapidly increases and charges the diode, resulting in a very low capacitance. This transient charges the surrounding circuit elements and helps to limit the voltage and current spikes. As the breakdown voltage is decreased, the capacitance of this device also decreases due to the decrease in the number of charge carriers on the device.

The V39ZS1PX2855 also offers high surge capability, meaning it can support high pulse amplitude and fast rise time. This is enabled by the device’s low capacitance characteristics as well as its high reverse breakdown voltage. In addition, the device provides fast recovery, meaning that it can quickly return to its normal state after a transient event. All of these features make the V39ZS1PX2855 suitable for a wide range of applications.

The V39ZS1PX2855 is a perfect fit for protecting low voltage and low power applications. It is capable of providing fast, reliable, and low-capacitance protection, enabling it to protect power supplies, interfaces, and input/output signals.
