Why Is Demand Increasing?

• Miniaturization of electronic equipment: Compact switching components help manufacturers reduce circuit-board space.
• Demand for electrical isolation: PhotoMOS relays support signal separation in sensitive measurement and control circuits.
• Medical and telecommunications applications: Reliable switching is important in instruments and communication equipment.
• Energy-storage and EV systems: Electrification creates additional applications for isolated switching components.

Fab & Technology Pulse: Optical Isolation Enables Compact Switching

PhotoMOS relays combine optical coupling with semiconductor switching to transfer control signals without conventional mechanical contacts. This design can offer low leakage, silent operation, and long switching life in suitable applications. Their performance depends on parameters such as on-resistance, switching speed, load current, isolation voltage, and operating temperature.

As electronic systems become smaller and more integrated, designers are evaluating PhotoMOS devices for applications where electrical isolation and compact packaging are important. Manufacturers must balance switching performance with cost, thermal behavior, and the requirements of the intended circuit.
