Surge protection technologies such as transient voltage surge suppressors (TVS) and metal oxide varistors (MOVs) are both effective solutions for protecting sensitive equipment from power surges. TVS devices are circuit protection components designed to detect and divert harmless voltage surges to ground, while MOVs are designed to absorb the excess voltage in order to protect the connected equipment.The TMOV14RP385M is a teardrop-shaped MOV that is designed for use on exposed PCBs. It is designed to provide surge protection for telecom and security applications and has an operating temperature range of -40℃ to +125℃. This device meets the UL 1449 4th Edition standard for performance in surge current environments and is designed to provide a high performance, cost effective solution.The TMOV14RP385M is constructed of a ceramic shell containing two layers of Zinc Oxide. The outer layer of the MOV is designed to dissipate the surge current and protect the PCB, while the inner layer functions as an absorber, absorbing and dissipating the remaining energy. The device is rated for a maximum surge current of 8kA and a maximum voltage of 230V, making it suitable for a range of applications, including telecom, industrial, and residential.In operation, MOVs work by absorbing the voltage generated by passing surge voltages. When the MOV is exposed to a surge voltage, the Zinc Oxide inside the device becomes a conductor and releases the energy as heat. This heat dissipates to the surrounding circuit board, where it is then safely dissipated. The MOV then returns to its open state, ready to respond to another surge.The TMOV14RP385M is a highly effective surge protection component, offering robust protection for a wide range of applications. Its ceramic shell materials provide insulation from the heat generated by the MOV, while its teardrop-shape allows the device to fit flush against a circuit board. It is also designed for easy mounting, allowing it to be mounted directly onto any exposed surface in order to provide reliable protection.In summary, the TMOV14RP385M provides an effective solution for surge protection of sensitive equipment. Its teardrop-shaped construction provides a secure fit to any exposed PCB, while its Zinc Oxide construction dissipates surge current and absorbs remaining voltage. This versatile surge protection device is suitable for a range of applications, including telecom, industrial, and residential, and is designed for easy mounting and fast response times.
