ROHM FET
FETs are field-effect transistors that are widely used as amplifier elements, switching elements and memory elements. FETs control the current between the source and drain with the voltage applied to the gate. An important feature of FETs is that the input resistance is high at the gate and power consumption is low, which makes thermal runaway difficult to occur. They are used in power amplifiers such as those for sound, high frequency and microwaves. They are also used in switching regulators because it takes a short time to switch the current between the source and drain on/off. FETs are broadly classified into J types and MOS types. Based on the MOS type, the enhanced CMOS type is used in devices such as CPUs and memory because the power consumption is extremely low, the size is small and suitable for integrated circuits, and manufacturing costs are low.
