THINKING introduces the new TVG series, an over-voltage protection component that integrates metal oxide varistor (MOV) and gas discharge tube (GDT) technologies in a standalone radial-leaded package. The TVG Series protector leverages the strengths of MOV and GDT to offer higher surge current withstand capability, minimal current leakages, low capacitance, reduced power consumption, and longer service life, providing more advanced over-voltage protection than conventional radial leaded MOV devices.

The max. continuous voltage of the components ranges from 150Vac to 550Vac and from 200Vdc to 745 Vdc. Offering 8/20μs maximum surge current ratings (Imax) of up to 6,000A and 10,000A, the TVG series provides excellent surge withstand capability in the compact sizes of Ф10mm andФ14mm. Furthermore, the protector can operate at temperatures of up to 125℃, surpassing the typical 105°C rating of most MOVs, and is well-suited for equipment operating in harsh environments. The aforementioned performance specifications make the TVG series product ideal for designers seeking to achieve design goals in light of space reduction, elevated operating temperature, and enhanced surge protection performance. The product is recommended for AC /DC power line voltage protection, electrical and electronic equipment required to comply with the IEC 62368-1 standard, and the applications listed below.

• ●  Solar inverter, energy storage system, EV charging station
• ●  Premium power supply, uninterruptable power supply (UPS), power distribution system, battery-powered equipment
• ●  Industrial equipment, smart meter, smart motor drive and control
• ●  Smart home appliance, high-end consumer electronics
• ●  Telecommunication equipment, power line communication system
   

MOV is a well-established solution for addressing over-voltage events in AC and DC line voltage because of its rapid response and high current handling capabilities. However, the leakage currents of standard MOV will increase and aggravate over time due to its prolonged exposure to line voltage transients, ultimately leading to degradation and failure. The TVG series product is a novel approach that overcomes the inherent limitations of MOV, offering improved safety, reliability, and surge handling performance. It provides the following design advantages over the widely adopted solutions.

• ●  The high insulation resistance of GDT helps lower the voltage across the MOV during normal operations, substantially minimizing MOV degradation over extended usage and thereby preventing failure in the integrated protector.
• ●  The TVG series product is robust and reliable because the high insulation resistance of GDT ensures minimal leakage current flowing through the MOV, effectively reducing power consumption and extending the lifespan of the protector.
• ●  This two-in-one component optimizes efficiency and space utilization compared to the configurations using a discrete MOV in series with a GDT device.
• ●  Low capacitances of the component help preserve signal integrity.
   

The TVG series sets a new standard in over-voltage protection technology. With unparalleled performance and reliability, the integrated protector is an ideal drop-in replacement for the same-size radial leaded MOV device. Designers can maintain the same circuit design while optimizing surge protection performance and space utilization.
