SUMMARY
Power MOSFET switches available in the market today include options that exceed a blocking voltage of 120 volts and can conduct over 30 amperes in the ON state, suitable for controlling loads exceeding 2500 watts. These components are typically priced at around 40 dollars or more. Manufacturers such as Infineon and Texas Instruments offer a range of suitable MOSFETs, while alternatives like SCRs, Triacs, and solid-state relays should also be considered for specific applications.
