SDD451

DC Input

Optocoupler

The SDD451 consists of a photo Darlington transistor optically coupled to a light emitting diode. Optical coupling between the input LED

and output phototransistor allows for high isolation levels while maintaining low-level DC signal control capability. The SDD451 provides an

optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation

circuitry.
