Working Principle of STP8N120K5

The STP8N120K5 is a type of MOSFET with a gate, drain and source. All of them are connected to an external circuit that provides electrical energy to the STP8N120K5. The gate is the terminal used to control the current flow through the MOSFET, by applying a voltage on the gate. The voltage applied to the gate controls the current which passes through the MOSFET, as the drain and source remain the same. Thus, one can limit the amount of current passing through the MOSFET by controlling the voltage applied on the gate, using the PWM.

When the voltage applied on the gate is low, the MOSFET acts like an open switch and the current will not pass through the device. When the voltage is high, the current passes through the MOSFET and it acts like a closed switch. Thus, the STP8N120K5 is used to control the switching of electrical loads, as the MOSFET will be constantly switching between the “ON” and “OFF” state, depending on the voltage applied on the gate.

The STP8N120K5 can be used in any application where the switching of high current is required, as it is capable of controlling higher voltages and currents than other types of transistors. The MOSFET has low on-resistance, low gate charge and improved dV/dt capabilities, which makes it suitable for use in applications such as motor control, power supplies, converters, and drive systems. The STP8N120K5 is also capable of operating at high switching frequencies and can handle a wide range of temperatures.
