The FDMC8676 MOSFET is a part of single n-channel power MOSFETs produced by ON Semiconductor. It is a 100V rated MOSFET, with a 0.019Ω RDS (ON) at 10V VGS and capable of continuous current of 73A. The MOSFET also has an exceptionally low gate charge, allowing it to be used in demanding power topologies.

The FDMC8676 has a wide range of applications, and is suitable for switch mode power supply design, such as those used in SMPS, inverters, and dimmers. The device also finds its application in low voltage solution, where it performs as high-side switch to limit inrush current. The device is also used for load switching and for emergency back-up power.

The working principle of this MOSFET is based on transistor-level switching, wherein gate voltage controls the current between the source and the drain of the MOSFET. The speed and amount of current depends on the characteristics of the equipment. When the gate voltage is low, the channel will be off, blocking the current and not allowing it to flow between the source and the drain. When increased, the gate voltage will exceed the threshold voltage and turn on the channel, allowing the current to flow through it.

The FDMC8676 is a cost-effective device that provides flexible, efficient, and reliable operation in demanding switch mode power supply applications. It is a suitable choice for use in medium-power circuits, providing fast switching with minimal switching losses.

When used in a controlled environment, the device offers reliable and accurate switching, with a high tolerance to voltage spikes and over-power. The device offers excellent thermal performance, allowing for the use of smaller packages for the same level of output, and eliminating the need for thermal dissipation.

In summary, the FDMC8676 MOSFET is an ideal choice for switch mode power supply applications due to its low RDS(ON) and gate charge, and its low voltage threshold, along with its fast switching speeds, making it suitable for a variety of applications. The device offers excellent thermal performance and is capable of withstanding voltage spikes and over-power. In addition, it is a cost-effective device that provides reliable and accurate switching while minimizing switching losses.
