Electrical Isolator Warning Signs

An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. [1] Opto-isolators prevent high voltages from affecting the system receiving the signal. [2]

Polyimide has lower stress than SiO2 and can increase in thickness as needed. SiO2 thickness, and therefore isolation capability, is limited; stress beyond 15 ยตm may result in cracked wafers during processing or delamination over the life of the isolator. Polyimide-based digital isolators use isolation layers as thick as 26 ยตm. Isolator Structure
