FCD820B Datasheet | Fairchild Semiconductor

Optically-Coupled Isolator Optoelectronic Products 5-6 FCD820/A/B/C/D General Description The FCD820 series of optoisolators bines a GaAs infrared-emitting diode and a silicon npn phototransistor in close proximity. Optical intercoupling provides a high degree of ac and dc isolation. A capability for continuous operation of the input diode results in a frequency response extending to dc. Connection to the transistor base is also provided for design flexibility. The FCD820 is covered under UL ponent recognition program, reference file E55299.
