Vishay is one of the world's foremost manufacturers of power MOSFETs. The Vishay Siliconix MOSFET product line includes a diverse range of advanced technologies in more than 30 package types, from the chipscale MICRO FOOT® and thermally advanced PowerPAK® families to the classic “TO” transistor outline. Single- and multi-die MOSFETs are available with integrated features such as Schottky body diodes and ESD protection, while our unique PowerPAIR® devices combine optimized combinations of MOSFETs for synchronous buck converters and other applications in a single package.
Both photocouplers/optocouplers and solid state relays (photo MOSFET or optical-coupled MOSFET (OCMOS FETs)) transmit signals while remaining electrically isolated, but there are some important differences. MOSFET devices are also applied in audio-frequency power amplifiers for public address systems, sound reinforcement and home and automobile sound systems. citation needed MOSFETs in integrated circuits are the primary elements of computer processors, semiconductor memory, image sensors, and most other types of integrated circuits.

PhotoMOS
A PhotoMOS is a semiconductor relay with an LED as an input and MOSFET as an output. It is used in various fields to improve device reliability and reduce size.
Obviously the PhotoMOS differ from the conventional electro-mechanical relays. PhotoMOS are classified to semiconductor relays that have no moving contact, therefore they are superior to conventional electro-mechanical relays in life-expectance and reliability of contacts, operation speed, and their sizes.
But they also distinguish themselves from other switching solutions that utilize photo-couplers, photo-transistors etc. PhotoMOS have MOSFET for output, therefore they are the most suitable devices for small analog signal switching.
Compared with Electro-Mechanical Relays have moving contact:
Compared with SSR (Solid State Relays) have phototriac for output:
●Longer lifetime (No limit on mechanical and electrical lifetime) ●Higher-speed and high-frequency switching ●Higher sensitivity (less power consumption) ●Smaller size ●Less contact problems such as arcs, bounce, and noise ●More resistant to vibration and impact ●No limitation for the mounting direction
●Able to control miniature analog signal ●Applicable to both AC/DC ●More sensibility ●Less leakage current ●Lower offset voltage ●Various contact structures such as 2a, 4a, 1b, 2b, and 1a1b in addition to 1a
