SDD400

SDD400
DC Input
Photo-Darlington Optocoupler
DESCRIPTION
The SDD400 consists of a Photo Darlington transistor optically coupled to a light emitting diode. Optical coupling between the input LED
and output Photo Darlington allows for high isolation levels while maintaining low-level DC signal control capability. The SDD400 provides
an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation
circuitry.
