Application Field

STB7NK80Z-1 MOSFET is often used in high-voltage, high-power applications such as solar inverters, UPS systems, and other related power control applications. It is suitable for control, rectification, and protection of power supply. It is used to control the level of current and power in the systems. STB7NK80Z-1 can also be used in DC/DC converters, AC phase controllers, and power distribution circuits.

Working Principle

A MOSFET operates on the same basic principles as other transistors; the current is controlled by the gate – source voltage. When no voltage is applied to the gate, the substrate is the same as the source. In this state, the Source-Drain current is limited only by the load impedance. When a Gate voltage is applied to the Gate-Source, the Substrate is pulled to the “Vgs-” level. This attracts majority carriers to the drain and moving it out of the Substrate. This reduces the number of carriers available to go from drain to source, limiting the drain current. Thus, by controlling the Gate voltage, the Source-Drain current can be controlled.

The STB7NK80Z-1 MOSFET has a very low threshold voltage of 2V and can operate with low gate voltage. This makes it attractive for applications requiring low voltage, while still providing efficient current control and high power handling capacity.
