TVS (Transient Voltage Suppressors), MOVs (Metal Oxide Varistors) and V321HB34 form an important microwave device group, which play a critical role in protecting sensitive electronic components from harmful transients. Transients are temporary spikes of high voltage or energy that can cause serious damage to electronic components, which can include permanent damage, or even complete failure of the component.

The V321HB34 is an especially important microwave device in this group, and it is most commonly used in switching power systems. These systems are used in all kinds of digital equipment, but due to their specific function, they are particularly important in the industrial or commercial sector.

The V321HB34 is designed to respond to over-voltage conditions by instantly discharging a high-energy current. Its unique design offers a superior level of protection in comparison to other microwave devices. To understand the working principle of the device, it is important to understand the operation of its two components – a special negative temperature coefficient diode and a nonlinear, semiconductor resistance element.

The special negative temperature coefficient (NTC) diode acts as both a temperature sensing element and a solution for protection from over-voltage surges. It functions as a rectifier, allowing current to pass only in one direction. In order to operate correctly, the diode needs to be exposed to a temperature that is lower than its set threshold level. The NTC diode then rapidly switches from its non-conducting state to a conducting state when the temperature falls below the threshold level. This sudden change creates a high voltage surge, which the device can then absorb.

The semiconductor resistance element is the other component in the V321HB34 device, and it operates differently. This element is responsible for providing resistance to current when the NTC diode conducts current. This ensures that the device does not become overloaded when responding to over-voltage conditions. Thanks to the semiconductor resistance element, the V321HB34 can safely absorb energy and dissipate it without causing any permanent damage to other components in the system.

The V321HB34 is an important microwave device, which has many important applications. It is most commonly used in switching power systems to protect other electronic components from over-voltage transients. Its unique design, which includes an NTC diode and a semiconductor resistance element, ensures reliable protection from transients. Thanks to its protection, a variety of digital equipment can safely operate, and the V321HB34 is therefore a critical component for many industries.
