Photocoupler
A photocoupler/optocoupler optically links, via a transparent isolating material, an infrared LED and a photodetector within one housing. Usually this detector is a phototransistor or a photodiode with some additional amplifiers. These devices are used for galvanic separation and protection of the inputs of microcontrollers.
The couplers are approved according to the most important safety approvals like VDE, UL,...
Main Features - DIL, SMD, Mini-flat (SOP) and SSOP-housing
- Single- and multi-channel-types available
- UL, VDE and TUV approved
- Stromübertragungsraten von 50-600%
- High-speed couplers available
- Isolating voltage up to 5.000V
