FCD820/A/B/C/D
General Description The FCD820 series of optoisolators combines a GaAs infrared-emitting diode and a silicon
npn photo
transistor 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 component recognition program, reference file E55299.
