TVS diodes are a type of protection device and are used in many appliances and electronic devices. The SM15T47AY is a transient voltage suppressorWith Standoff designed to protect a variety of critical devices from over-voltage transients. This article will discuss the application field of SM15T47AY as well as its working principle.

Application field of SM15T47AY

The SM15T47AY is designed primarily for protection when transients occur, and offers general protection. This protection comes in many forms such as over-voltage protection, surge protection, and ESD protection. The SM15T47AY is ideal for use in many electronic devices including computers, communications equipment, audio-visual equipment, home appliances, and other electronic products. Further, this diode is is ideal for automotive electrical system protection, as it can protect signal paths, radio receivers, and power lines in cars.

Working principle of SM15T47AY

A TVS diode is a transistor-like device that helps prevent damage to circuits by providing bi-directional transient voltage protection when transients occur. When an over-voltage transient occurs, the SM15T47AY rapidly turns on and diverts the transient to ground, thereby clamping the voltage, and protecting the sensitive electronic components. The protection rating, or breakdown voltage, of the SM15T47AY is 150 volts.

The SM15T47AY has a stand-off voltage of 36 volts. This is the voltage that the diode must reach before it activates and begins conducting. This is important in order to protect components that are only exposed to small voltage swings. When the voltage rises above the stand-off voltage, the diode will start conducting and the additional voltage is diverted to ground.

The stand-off voltage of the SM15T47AY is adjustable. This is useful for applications that require different types of protection depending on the situation. If the voltage exceeds the stand-off voltage, the diode starts conducting and the extra voltage is diverted to ground. When the voltage falls back below the stand-off voltage, the diode stops conducting and the protection is turned off.

The SM15T47AY not only provides over-voltage protection but also provides protection from electrostatic discharge (ESD) and surge protection as well. When an ESD event occurs, the diode rapidly turns on and diverts the high voltage to ground, protecting the sensitive electronic components from damage. In the event of a surge, the diode will turn on and divert the surge energy away from the sensitive components, protecting them from damage. Lastly, the diode will provide limited reverse voltage protection, ensuring that any sparks from static electricity or other sources will not damage the electronic components.

Conclusion

The SM15T47AY is a transient voltage suppressorWith Standoff diode that is designed to provide protection against over-voltage, ESD, and surge protection. It can be used in many different applications including computers, communications equipment, audio-visual equipment, home appliances, and other electronic products. Its stand-off voltage can be adjusted to suit different protection needs. Finally, it provides limited reverse voltage protection, ensuring that sparks from static electricity will not damage the sensitive components.
