Photocouplers Market 2025-2032

The global Photocouplers Market was valued at 2488 million in 2024 and is projected to reach US$ 3887 million by 2031, at a CAGR of 6.7% during the forecast period.

Photocouplers Market Overview

An optocoupler, also known as an optoisolator, is an electronic component that enables the transfer of electrical signals between two isolated circuits using light. This component typically comprises:

• A light-emitting diode (LED)
• A photosensitive device such as a photodiode, phototransistor, or photovoltaic cell
• All enclosed in a single package

The key function of an optocoupler is to provide electrical isolation, which helps prevent high voltage in one circuit from affecting or damaging another, while still enabling reliable signal transmission.
