MOSFETs, or Metal-Oxide Semiconductor Field-Effect Transistors, are by far the most common FETs in both digital and analogue circuits.  The 'Metal' in the name is an anachronism from early chips where gates were metal – modern chips use polysilicon gates.

MOSFETs with fast diodes

• These are ideal for power switching applications.  Incorporating a rugged fast diode into the MOSFET improves the dc/dt performance of the device and very often eliminates the need for additional fast freewheeling diodes.

N&P Channel MOSFETs

• Also referred to as NMOS and PMOS, these are the basic MOSFETs designed to provide superior performance and ruggedness in high-voltage applications.

HF MOSFETs

• MOSFETs are very good at switching very high frequencies.  In some applications “very high frequencies” is not enough and MOSFETs for the multi-megahertz range are needed.

Low on resistance MOSFETs

• The on-resistance of power MOSFETs tends to increase with temperature.  Waste heat lost on this resistance causes more heating of the junction, further increasing the temperature.  New production processes have therefore been developed to reduce the on-resistance
