Introduction to the SMA5118

The SMA5118 is a 60-volt, N-channel MOSFET Array that includes six single power MOSFETs configured as a cascode switch. This switch offers superior performance with low switching losses, reducing the need for additional heating elements in power converters. It can also be used in discrete applications such as DC-DC & AC-DC converters, transient voltage suppressors and controlled rectification.

SMA5118 Application Field and Working Principle

The SMA5118 is a great choice for applications requiring an efficient and low-cost solution. Due to its great performance, the SMA5118 works best in power converters as it is able to reduce switching losses while offering superior noise immunity, making it ideal for use in wide range of streetlight, automotive, and industrial applications.

The SMA5118\'s basic principles of operation are fairly simple. The MOSFET Array consists of six N-channel MOSFETs connected in a cascode configuration. The MOSFETs are connected in series and the gates of each successive transistor are tied together at the gate of the first transistor. This configuration ensures that each MOSFET is conducting in the same direction, creating a single-unit device capable of providing up to 60 volts of power with minimal switching losses.

The SMA5118 also includes integrated protection features, such as over-temperature, over-current, over-voltage and under-voltage protection. The integrated protection features ensure that the MOSFET array will remain safe and reliable even during extreme operating conditions.

Conclusion

The SMA5118 is a highly efficient and low-cost solution for power converters. Thanks to its cascode configuration and integrated protection features, the SMA5118 is able to reduce switching losses while maintaining excellent noise immunity. Additionally, the SMA5118 is able to provide up to 60 volts of power with minimal switching losses, making it an ideal choice for applications requiring high efficiency and reliability.
