A TVS (transient voltage suppressor) diode is an electronic component that is designed to provide protection to sensitive electronic components from high-voltage transients such as electrical surges and electrostatic discharge. The ATV02W640B-HF is a type of TVS diode notable for its high-frequency transient protection capabilities. It is a double-line TVS diode with both types of protection available in one package.

The ATV02W640B-HF is an ideal device for applications such as automotive, industrial, LED lighting, medical equipment, etc. that require protection from high-frequency transients. It can also be used in consumer electronics applications, such as computer, television, and cellphone charging stations. It has an ultra-low power bi-directional peak power dissipation capability of up to 640W, and is available in SOT-353, D2PAK, and DPAK packages, making it highly compatible with various circuits and arrays.

Application Field:

The ATV02W640B-HF can be used for a variety of high-frequency transient protection applications. It is designed to provide protection from electrostatic discharge (ESD) and electrical surges, and is suitable for usage in automotive, industrial, and consumer electronics such as computers, televisions, and mobile phone charging stations. The ATV02W640B-HF is capable of suppressing overvoltage transients up to 2.7kV, providing a reliable level of protection in harsh environments.

Working Principle:

The ATV02W640B-HF operates by creating a low-resistance path for the transient current. In the event of an electrostatic discharge or other transient surge, the device will conduct the high voltages away from the protected circuit. The device will then return to its normal state when the input voltage returns to its normal operating level. Additionally, the ATV02W640B-HF provides both bi-directional and unidirectional protection. The bi-directional protection provides the necessary protection against both positive and negative transients. The unidirectional protection is only effective against positive transients.

Conclusion:

The ATV02W640B-HF is an ideal TVS diode for applications that require both high-frequency transient protection capabilities. It is a double-line TVS diode and is capable of suppressing overvoltage transients up to 2.7kV. Its ultra-low power peak power dissipation capability and wide variety of available packages make it highly compatible with numerous circuits and arrays. It is an excellent choice for radiation-sensitive and extreme-environment applications such as automotive, industrial, LED lighting, medical, and consumer electronics.
