Its low profile design and low on-state resistance make it suitable for use in energy saving systems.

Working Principle

The STB85NF3LLT4 MOSFET works on the same principle as other MOSFETs, wherein current is allowed to flow through the device based on the voltage that is applied to the gate. When the gate of the MOSFET is charged to a high voltage, the current will flow from the source via the drain, allowing charge to be transferred from the source to the drain. This allows for high power switching at low power losses.

The STB85NF3LLT4 can switch at a high voltage and high current level and is capable of conducting very high currents with a very low on-state resistance. This makes it an ideal component for power components, high power switches and fan speed controls. The device is also capable of operating over a wide temperature range, making it ideal for application in various power systems.

The STB85NF3LLT4 also offers excellent current-handling capability and allows for very high current to be released almost instantaneously when the drain is at a high voltage. This makes it perfect for use in motor controls and speed controllers. It also allows for greater power savings due to its low on-state current and low gate charge.

The STB85NF3LLT4\'s low RDS(ON) resistance also allows for efficient heat dissipation and improved efficiency of the application. It also provides superior device reliability due to its rated avalanche energy and its strong gate-drive capability.

In summary, the STB85NF3LLT4 MOSFET is a highly efficient and reliable device that can be used in various applications such as high-frequency rectification, surge protection, inrush current limiting, motor control, speed control, power field conversion and energy saving systems. Its low on-state resistance, high current capability, excellent thermal design and impressive reliability makes it ideal for use in power systems.
