ROV05H621K-S belongs to the Varistors, MOVs of Transient Voltage Suppressor (TVS) product family. Made of zinc oxide, Varistors, MOVs use a metal oxide semiconductor to guard against voltage transients and surges. As a low voltage component, the ROV05H621K-S offers excellent security protection and wide voltage range.

ROV05H621K-S is a non-pole radio frequency interference (RFI) suppression device that is an excellent fit for applications including cell phones, USB power supplies, digital cameras, tablets, microcontrollers, and circuit boards. It features a wide operating voltage range from 4V-24V, a high surge current capacity up to 1,000A, and a low clamping voltage of 6.21V when subjected to an 8/20-μs surge.

The ROV05H621K-S also features an ESD protection capability up to 8KV, and is designed to protect circuit boards from damage due to electrostatic discharge (ESD) and lightning. This device has a low leakage current of 0.01μA, and a capacitance range of 13.4pF, making it ideal for low power applications. It has a small size of 5.0 x 3.2 x 3.2mm, and a maximum capacitance of 15pF.

The working principle of the ROV05H621K-S is based on the operation of a zinc oxide varistor. When subjected to a voltage pulse, the voltage on the surface of the semiconductor increases quickly, forming an avalanche breakdown to reduce the voltage applied on the surface of the semiconductor. This process creates a voltage limit that clamps the voltage, protecting the system from transients and surges.

The ROV05H621K-S is designed to offer superior protection against voltage transients and surges, making it a great fit for applications requiring a wide operating voltage range in addition to RFI/EMI protection. This device also offers excellent ESD protection capabilities, making it an ideal choice for applications that must withstand sudden, high-voltage electrostatic discharges. This device has a low leakage current and a small size, making it a great fit for low power applications.
