Introduction to TVS - Diodes

A transient voltage suppressor (TVS) diode, also known as a unidirectional movable gap diode, is a specialized three-terminal semiconductor device used to protect low-voltage electronic systems from electrostatic discharge (ESD) and power line impulses. TVS diodes, or transient voltage suppressor diodes, are a form of diode used in electronic circuits to provide over-voltage protection due to over-voltage transients, electrostatic discharges (ESD) and other voltage-related problems.

SM6S22-E3/2D Application Field and Working Principle

The SM6S22-E3/2D is a uni-directional silicon voltage suppressor diode, capable of handling repetitive voltage up to 5.6 watts, which is ideal for medium power switching applications. It is designed to protect against transient voltage spike such as those caused by lightning strikes, electrical shorts, and automotive ignition systems. The device is capable of dissipating up to 600V and has a standard working current of 150mA. The basic function of the SM6S22-E3/2D is to shunt high energy spikes away from sensitive electronics and to provide protection to support ease of operation and widespread coverage. The diode works by allowing a current to flow through it in only one direction. When external voltage exceeds the diode\'s breakdown voltage, it begins to conduct and acts like a low resistance path. This allows the current to be diverted away from the protected circuit, thus reducing the amount of energy present in the circuit.The SM6S22-E3/2D can be applied in a wide range of medium power switching applications, including relays, motors, and solenoids. It can also be used in electronic consumer and automotive products like cell phones, laptops, and cars.

Conclusion

TVS diodes, including the SM6S22-E3/2D, are used in a number of applications for providing protection from transient voltage spikes. By allowing current to flow only in one direction, they protect sensitive electronics from overvoltage. The SM6S22-E3/2D is an ideal diode for medium power switching applications, providing 600V with a standard working current of 150mA.
