Isolator Definition and Category Description

What is an isolator?

An isolator is an electronic device or component used to transfer signals or electrical energy between two electrical circuits while maintaining electrical isolation between them. This isolation prevents high voltage, noise or other interference from propagating from one circuit to another, ensuring the safety and reliability of the system. Isolators are widely used in industrial control, communications, power management and other fields.

Types of isolators

Common types of isolators include optoelectronic isolators, digital isolators, capacitive isolators, transformer isolators, and magnetic isolators. In addition to isolators,Dasenic also provides isolator-related products such as: special purpose isolators, isolated gate drivers, transistor & photovoltaic output photosolvents, TRIAC and SCR output photosolvents.

Isolator products are used where it is necessary to pass information, control signals, or gate drive signals between portions of a system that must not have a direct electrical connection with each other, whether for functional or safety-related reasons. Within this category, devices are further organized according to the character of their output stages; some device outputs behave like transistor, others like logic gates, photovoltaic (solar) cells, thyristors, or photoresistors.
