TVS or transient voltage suppressor devices are designed to protect a circuit and its components from damage due to voltage transient events. These voltage transients in a typical circuit can occur when various sudden changes in current take place such as those caused by motor start-ups, relay contacts switching, and lightning strikes. These devices can also be used to prevent the passage of high-voltage, high intensity electrical energy that can potentially cause circuit damage when connected to a sensitive device. Another type of voltage protection device is the MOV; which is an acronym for Metal Oxide Varistor.

A TVS device such as the NibaTech V100ZA05P, is a bi-directional voltage protection device that is designed to dissipate excessive electrical energy by generating a voltage clamping action to limit the peak voltage level during an electrical surge. The clamping voltage of the V100ZA05P is 5 volts along with a peak-current pulse rating of 25 ampere per 10/1000 microsecond. Its working voltage range is from 4.8 to 12 V and its transient voltage range is from 2.1 to 12 V. This device is UL 94V-0 and MIL-STD-750 certified and UL 510 approved.

In the application field, the NibaTech V100ZA05P is used in many different areas. It is particularly favored for use in computer networks and data communication systems such as Ethernet, Modem connections and Fibre Optic systems which require reliable surge protection due to the sensitive nature of the data. The V100ZA05P is also used in applications such as automotive ECU due to its excellent ESD (Electro static discharge) protection capability. Furthermore, this particular device has an impressive noise and transient immunity due to its low capacitance and capacitive discharge characteristics.

The working principle of the NibaTech V100ZA05P is fairly simple. When a transient voltage increases above the clamping voltage of the device, or if the current pulse exceeds the peak current rating, the device will begin to conduct and provide a low impedance path to ground to divert the extra energy. This action limits the rising voltage to the clamping voltage of the device, and the amount of energy present at the point of connection is minimized allowing the circuit and connected components to remain protected. These devices have a built in thermal shutdown feature that activates when the device temperature rises above a specified level, thus disconnecting the device from the circuit and preventing further damage.

The NibaTech V100ZA05P is a reliable device that offers a high level of protection from voltage transients and current pulses. It is an ideal choice for protecting circuits and components in highly sensitive and exposed operations such as computer networks and data communication applications. It is also well suited for automotive ECU and for general consumer and industrial applications.
