SMF43AT1G

TVS - Diodes

Transient voltage suppression (TVS) diodes, or sometimes referred to as Transient Voltage Suppressors (TVSs), are a class of semiconductor diodes specifically designed to protect sensitive electronic circuits against the destructive effects of electrostatic discharge (ESD). TVS diode technology provides enhanced surge and transient voltage protection.

SMF43AT1G Application Field and Working Principle

The SMF43AT1G is aMOSFET-styleTVS diode. It is used typically as a low-capacitance protection device against the electrostatic discharge, or ESD, that can damage or malfunction electronic circuits. It is rated for an avalanche rating of 500 watts peak pulse power per line, supply voltage of 7.0V or less, and a storage junction temperature of -65℃ to 150℃.
When a transient voltage is generated within the circuit, the SMF43AT1G\'sMOSFET-style construction triggers, preventing the surge from reaching the electronics that require protection. The transient voltage is diverted around the internal semiconductor junction, leaving the electronics undamaged and continuing operation.

The SMF43AT1G is available in anstatic independent flexible (FTP), micro-leadedpackage. This package allows for a low PCB footprint, and increases performance, providing superior transient and ESD protection while maintaining low clamping voltages. The SMF43AT1G can be used in multiple PCB designs such ascellular/smart phones, laptops, tablets and cameras, as well as automotive and industrial applications.

In summary, the SMF43AT1G is a MOSFET-styleTVS diodethat provides reliable, low-capacitance protection against electrostatic discharge and transient voltages. It has an avalanche rating of 500 watts peak pulse power per line, and is available in a flexible, low-profile package that allows for easy integration into a variety of electronic applications.
