Schematic diagram of an opto-isolator showing source of light (LED) on the left, dielectric barrier in the center, and sensor (phototransistor) on the right [note 1]. 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]
Figure 1: The optical circuit symbol for an isolator Faraday effect. The main component of the optical isolator is the Faraday rotator. The magnetic field, , applied to the Faraday rotator causes a rotation in the polarization of the light due to the Faraday effect. The angle of rotation, , is given by,
A schematic pinout of an extremely simple opto-isolator device. Often diode and transistor protection and/or amplification will be added. The dashed line in the centre represents to isolation barrer, over which no electrical contact can be permitted.
Opto-isolator: often changed to "U" for IC P: Plug (most-movable connector of a connector pair), plug connector (connector may have "male" pin contacts and/or "female" socket contacts) PD: Photodiode: Q: Transistor (all types) R: Resistor: RN: Resistor network: sometimes simplified to "R" for resistor, or "N" for network RT: Thermistor
Opto-isolator VTL2C1 with LED input and photoresistor output. Resistive opto-isolator (RO), also called photoresistive opto-isolator, vactrol (after a genericized trademark introduced by Vactec, Inc. in the 1960s), analog opto-isolator [notes 1] or lamp-coupled photocell, [1] is an optoelectronic device consisting of a source and detector of light, which are optically coupled and electrically ...
DIN-EN/IEC60747-5-5, 1,414Vmax peak isolation voltage, 8,000Vpeak transient isolation voltage rating (approval pending) 10Mbps data rate. 20kV/μs minimum CMTI. High-speed AlGaAs LED. Open ...
An opto-isolator is a very popular method of isolation in digital circuits. Cross-section of dual in-line package opto-isolators. Relative sizes of LED (red) and sensor (green) are exaggerated. Everlight EL817 phototransistor opto-isolator in DIP-4 package Halo TG110-S050N2RL 10/100BASE-TX Ethernet pulse transformer in SO-16 package.
Reference should be made to codes and standards. For example, IEC 60027, and Letter Symbols in Electrical Technology. Here are tables of widely accepted symbols. They are meant to be a guideline: Using the same symbols for the same things in different articles will increase their consistency, making them easier to understand and to improve.
