TVS (transient voltage suppression) diodes are essential components for safeguarding electronic equipment from power surge caused by electrostatic discharge, cables inrush current, and lightning. VLIN1626-02GHE3-18 is one of the most popular models in the TVS diode family. It presents an application field and working principle as follows.

Application Field

VLIN1626-02GHE3-18 is typically used in industrial, automotive and consumer applications, such as reverse blocking, automotive safety systems, steering systems, airbags, IC protection circuits, power supplies, HVAC system, renewables energy systems, and solar inverters, etc.

Working Principle

TVS diodes such as VLIN1626-02GHE3-18 features a bidirectional transient voltage surge clamping capability to protect sensitive electronic components from induced spikes in the power line source. It can greatly reduce the radiant energy impulse at the secondary side of the circuit by cutting off the high-voltage voltage entering the circuitry. In operation, when the power supply voltage rises too high or drops too low, the TVS diode will enter into a avalanche breakdown state, effectively shunt away most of the surge current away from the protected components.

The avalanche breakdown of the diode is a process wherein electrons accelerate their movement due to a strong electric field. This complicated process is established based on the characteristics of the p-n junction, which forms an electric field allowing the electrons to flow from the p side to the n side of the diode. When the voltage applied to the diode exceeds the breakdown capacity, the p-n junction initiates current conduction in the avalanche mode, thus limiting the voltage surge.}

TVS diodes are ideal for reducing transients of turn-on/turn-off events, which are prevalent in switching mode power supplies, and HVAC systems. They are now widely used to reduce transient surge levels encountered in power lines, battery systems, and power supplies. VLIN1626-02GHE3-18 diode is designed to protect the sensitive components from high-voltage spikes and transients by providing a very low clamping voltage and a fast response time.
