SDD601
DC Input
Optocoupler
The SDD601 consists of a photo Darlington transistor optically coupled to a light emitting diode. Optical coupling between the input LED
and output photo Darlington transistor allows for high isolation levels while maintaining low-level DC signal control capability. The SDD601
provides an
optically isolated method of controlling many interface applications such as telecommunications, industrial control and
instrumentation
circuitry.
