FCD825D - Optically-Coupled Isolator

Download the FCD825D datasheet PDF. This datasheet also covers the FCD825 variant, as both devices belong to the same optically-coupled isolator family and are provided as variant models within a single manufacturer datasheet.

Description

The FCD825 series of optoisolators have a npn silicon Planar phototransistor and a GaAs diode 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.
