TMOV20RP300EL2T7

The TMOV20RP300EL2T7 is an overvoltage and transient protection device that falls under the TVS - Varistors, MOVs category. It is designed for both line-to-ground and line-to-line applications, providing surge protection for a wide range of power and electronic circuits. This product is especially suited to protect sensitive power line circuits, and is well-suited for applications like power supply converters, military gear, network equipment, and consumer electronics.

The TMOV20RP300EL2T7 has a variety of features - thermally protected with a wide range of voltage thresholds, low capacitance, low profile, and radiation hardened for highly reliable performance. Its low capacitance helps reduce line noise, and its low profile helps reduce bulk in applications where space is at a premium. It also features overvoltage protection on the lines it is connected to, as well as providing transient protection for highly sensitive electronics.

The TMOV20RP300EL2T7 utilizes a thermally protected Varistor MOV (metal-oxide varistor) device, as determined by the Varistor suffix in the model number. This device utilizes a semiconductor layer of zinc oxide grains surrounded by metal layers. In the presence of voltage events, the grains exchange electrons, allowing current to flow from its positive to its negative terminal. The voltage rating of the MOV determines its response time, where higher voltage ratings typically imply quicker response times. Additionally, higher levels of charge will also cause the MOV to discharge more quickly.

The TMOV20RP300EL2T7 also utilizes an electrolytic capacitor to provide limited energy storage for transient events. The capacitor will dissipate stored energy safely, thereby providing overvoltage protection. The TMOV20RP300EL2T7 also features a ‘Reverse Stand-Off Voltage’ which determines the level of reverse voltage which the varistor is designed to operate under. Reverse voltage flow occurs when the MOV is subject to a backflow, such as an overvoltage. It is this reverse voltage which will trigger the varistor and provide overvoltage protection.

In summary, the TMOV20RP300EL2T7 is a thermally protected Varistor MOV designed for line-to-ground and line-to-line applications, offering a wide range of voltage thresholds, low capacitance, and low profile. It is ideal for sensitive power line circuits, and for applications where overvoltage and transient protection are desired. The TMOV20RP300EL2T7 utilizes a zinc oxide semiconductor layer alongside an electrolytic capacitor to provide energy storage and overvoltage protection. An internal Reverse Stand-Off Voltage determines its response to backflow scenarios, providing an additional level of protection.
