V39RA8

V39RA8 is a Gas Discharge Tube (GDT) that belongs to a family of structural components known as Transient Voltage Suppressors (TVS). The development of such components was motivated by the need to protect sophisticated electronic systems from the ravages of electromagnetic disturbances. TVS are widely used for a variety of circuit protection applications across a variety of fields, such as aerospace, automotive, telecommunications, consumer electronics, and more. This article will look at the application field and working principle of V39RA8.V39RA8 is designed to provide effective protection against overvoltage transients in applications such as telecommunications, computers, motor and generator drives, and many other circuits that are sensitive to overvoltage stress. It has a wide operating temperature range of -55°C to 170°C. The unique design of V39RA8 allows it to operate at higher energy levels than conventional varistors, while also providing enhanced immunity to false triggers. It is available in various capacitance ratings, depending on the application needs.The operating principle of V39RA8 is quite simple. When an overvoltage transient event occurs, the cathode of the GDT is exposed to an increased electron emission current. This current is then stored in a capacitance that is in parallel with the GDT, which is used to limit the surge current. When the transient event has passed, the voltage drops to a low level, and the stored energy is then dissipated in the form of thermal energy. This process of protection is known as \'self-regulating-clamping’.In terms of applications, V39RA8 can be used for circuit protection in a variety of circuits, including isolated DC power supplies, transformers, and bus bars. It can be used for surge protection in a variety of applications, including power supply networks, instrumentation, automotive, and many other fields. Furthermore, V39RA8 can be used for overvoltage protection in environments where high levels of electromagnetic fields are present, such as in industrial machinery, waveguide filters, and medical imaging.As one of the most versatile, reliable, and cost-effective TVS components, V39RA8 is an excellent choice for a wide range of circuit protection applications. Its highly efficient operation, wide operating temperature range, and excellent immunity to false triggers make it an ideal solution for many protection challenges.
