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. FEATURES High Load Voltage (Vceo = 300V MIN) High current transfer ratio (600-9000%) High input-to-output isolation package (5000 Vrms) Compact 4pin DIP package RoHS / Pb Free / REACH Compliant device OPTIONS/SUFFIXES* -H .04" (10.16mm) lead spacing (VDE0884) -S Surface Mount Option -TR Tape and Reel Option NOTE: Suffixes listed above are not included in marking on device for part number identification.
