TVS-Varistors, MOVs are widely used in today’s electric field due to their electrical stability, low price and easy installation. One such product, the ROV14H121K, is a three-terminal device that provides Good Junction Protection and is suitable for use in circuit protection applications.

The ROV14H121K is an N-channel power MOSFET. It employs a drain-source breakdown voltage of 14V with an operating drain current of 10A. It is of the popular TO-252 package and is commonly used in circuit protection design. This MOSFET is designed to protect sensitive equipment from overvoltage and overcurrent conditions. It also provides an adjustable overvoltage protection by utilizing an external resistor.

The ROV14H121K utilizes a PN-junction which provides a low turn on voltage. When the source voltage rises, the device starts conducting and a termination threshold voltage is reached where the device then switches off quickly. This overvoltage protection circuit utilizes the principle of current limiting which reduces the energy of an overvoltage connected to sensitive electronic components. Thus, the ROV14H121K protects the connected components from transient overvoltage and other hazards.

The ROV14H121K is commonly used in protection circuitry for AC/DC power supplies, TVS diode protection networks, surge protectors, surge suppressors, AC power spike protectors and other circuit protection applications. Its drain-source resistance is typically 0.1 ohms, so it can handle relatively high surge current. It is also widely used in Li-ion battery protection circuits and automotive systems. Furthermore, in consumer electronics, it can be used in laptop power protection and USB port protection circuits.

In summary, the ROV14H121K is a device with many applications in TVS-Varistors, MOVs and circuit protection applications. Its high power MOSFET and low turn-on voltage allow it to be used widely in circuit protection circuits and other power applications.
