TVS - Diodes Application Field and Working Principle

Transient Voltage Suppressors (TVS) are widely used in all types of electronic circuits to secure the device from voltage transients and surges. They use two diodes connected in reverse-parallel to shunting the voltage spikes often occurring in the circuit. They absorb the excess energy during an overvoltage pulse and dissipate the energy without dissipating the device. The SMB10J15A R5G is a small signal diode TVS that offers significant advantage in protecting the circuit against electrostatic discharge and electrical noise. This article will discuss the application field and working principle of the SMB10J15A R5G.The SMB10J15A R5G is a low-voltage diode TVS with a breakdown voltage at 15V. It is intended for use in automotive, high-speed switching, and industrial applications. Its low turn-on voltage and low capacitance make it the ideal choice for voltage spike protection in small signal circuits. The diode is available in a small SOD-123 package that is easy to mount and provides space savings in devices with high-speed switching.The SMB10J15A R5G is optimized for transient bursts with a second breakdown voltage at 8 V. It has a unidirectional construction with a low capacitance typical of 1pF and a low recovery time of 5ns. Its high peak current able to support 20A will reduce the number of components needed to absorb high voltage events.The device acts as an overvoltage absorber when connected between two points. It works by shunting the voltage spikes that occur in the circuit. When a transient voltage is induced by an electromagnetic field, the diode is triggered and the voltage spike is shunted to ground. This is the same effect as a zener diode, but it happens much faster. The diode also has a low capacitance, which means it can respond quickly to transient events.The SMB10J15A R5G has a wide range of applications. It can be used in circuits that require fast response times, such as relays or other control circuits, or in circuits required to absorb large voltage transients or noise. It can be used in high-speed switching applications where overvoltage transients or spikes are common, as well as in automotive and industrial applications.In conclusion, the SMB10J15A R5G is a low-voltage diode TVS with a breakdown voltage at 15V and a second breakdown voltage at 8V. It is intended for use in automotive, high-speed switching, and industrial applications where transient surges or noise must be absorbed. It has a low capacitance and a low recovery time, making it ideal for voltage spike protection in small signal circuits. Its high peak current able to support 20A will help reduce the number of components needed to absorb high voltage events.
