Technical content

The SDT450 consists of a phototransistor 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 SDT450 provides an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry.
