SDD400

DC Input

Photo-Darlington

Optocoupler

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.
