There’s a need to understand how PhotoMOS devices use optically coupled LEDs and MOSFETs to provide galvanic isolation up to high voltages, so you can design systems that maintain signal integrity while protecting your users and equipment from hazardous ground faults and high-voltage transients. This guide explains how isolation is [...]
Reliability matters when you design systems that must run without failure: PhotoMOS relays give you no moving parts, which eliminates contact wear, arcing and welding that commonly cause mechanical relay failure, and they deliver longer MTBF and consistent switching over millions of cycles. You get quieter operation, faster switching, reduced [...]
Relays using PhotoMOS technology let you achieve galvanic isolation and ultra-low leakage for higher accuracy, while offering long life and no contact bounce; you must still respect voltage and thermal limits to prevent measurement drift or damage, and design your switching strategy to preserve signal integrity and safety. Types of [...]
This guide shows how PhotoMOS solid-state relays and electromechanical relays differ so you can choose the right switch for your design: PhotoMOS offers no mechanical wear, fast switching, and low contact bounce, while electromechanical relays provide higher voltage/current handling and clear galvanic isolation; however, be aware of contact arcing and [...]
There’s a growing role for PhotoMOS relays in automated test and measurement where galvanic isolation and ultra-low leakage let you measure small signals without contamination; you can exploit their fast switching and long life to increase throughput while reducing maintenance, but you must mitigate overvoltage, thermal dissipation, and potential failure [...]
