Transient voltage surge suppressors (TVSs) and metal oxide varistors (MOVs) are the most common components used in protection circuits in order to protect sensitive circuits and equipment from damaging voltage transients. The ROV14-121K-2 is one such component; it is a radial leaded, high-performance, robust voltage surge suppressor designed specifically for I/O and C/M port protection. This component offers reliable protection against electrostatic discharge (ESD) and is designed to meet the IEC 61340 ESD protection standards.

This device utilizes metal-oxide varistors (MOVs) as the main components. This type of suppressor works by utilizing a large number of MOVs arranged in a radial array, forming a compact package. During normal operation, these components are "OFF" and will not interfere with the normal operation of the protected circuits. However, when a voltage transient or surge occurs, the MOVs will start to conduct and divert the surge away from its intended destination. This is accomplished by creating a low-impedance path to ground, which can dissipate the surge energy and protect the sensitive circuit.

The ROV14-121K-2 is designed to handle a wide range working voltages and peak pulse currents. It provides excellent surge protection performance with a maximum peak pulse current of 2.9KA for 10/1000μS pulses and a maximum working voltage rating of 2KV. It also offers excellent ESD protection with a maximum ESD Test Voltage of 18KV. The device is capable of withstanding up to 1000 repetitive ESD discharges with only a minimal performance degradation.

The robust design of this device also ensures that it can withstand environmental extremes. Its operating temperature ranges from -55°C to +125°C and its humidity resistance is rated at 85°C for 85% relative humidity (non-condensing). This makes the ROV14-121K-2 ideal for a wide range of applications, including industrial, automotive, and consumer electronics.

In summary, the ROV14-121K-2 is an excellent TVS-MOV component, designed specifically for I/O port and C/M port protection from voltage transients and ESD discharges. It has an excellent surge protection performance with a maximum peak pulse current of 2.9KA and a maximum working voltage rating of 2KV. Furthermore, it is highly robust and can withstand a wide range of environmental extremes. This makes it an ideal choice for a wide range of applications.
