TVS - Diodes

TVS diodes are an essential component in the electronics industry and have a wide range of applications. The VTVS47ASMF-M3-08 is a TVS diode from Vishay Semiconductor’s SFR series. It is designed to protect sensitive electronic components from transients and noise such as ESD, lightning discharges and other high surge events.

Applications

The VTVS47ASMF-M3-08 is particularly useful in automotive applications such as automotive switches, motors, lights, and other automotive electronics. It is also used in other applications such as personal computers, telecommunications components, and consumer electronics, as well as in industrial and medical electronics.

Features

This particular device is a 5mm terminal surface mount device. It provides a high level of over-voltage protection, with a peak pulse power rating of 47A and a maximum peak working voltage of 8V. It is RoHS compliant and comes in a variety of packages, making it suitable for a wide range of applications.

Working Principle

The VTVS47ASMF-M3-08 is a unidirectional TVS diode. When there is a surge of voltage or a spike in current, the diode will switch on and act as a high-speed bidirectional clamp to protect the circuit. This will limit the surge voltage and current to safe levels and prevent damage to the electronic components.

It is designed with a piezoresistive construction which allows for an ultra-low clamping voltage and increases the pulse handling capability. The built-in thermal protection will also protect the circuit from damage caused by excessive heat dissipation.

Conclusion

The VTVS47ASMF-M3-08 is a robust and effective TVS diode capable of providing superior protection against transients and noise. It is suitable for a wide range of applications and is an essential component in modern electronic circuits.
