05.ACSL-6xx0 堆栈式 LED 带来高度集成的光电耦合器产品

资料介绍
Optocouplers are widely used in providing galvanic isolation because of their true isolation characteristics. The heart of a modern optocoupler is an input infra-red-emitting LED and an output photodetector, sepa-rated by a light transmissive medium, that can also act as an insulation layer. Or an additional light transmis-sive dielectric layer can be added to provide insulation. The photodetector can be a phototransistor, a photo-diode with a transistor, or an integrated detector/logic integrated circuit. Most optocouplers are certifed to the basic safety standards as outlined by UL1577, CSA and IEC/DIN EN/EN 60747-5-2.
