SDD450
DC Input
Photo-Darlington Optocoupler
DESCRIPTION
The SDD450 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 SDD450 provides
an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation
circuitry.
FEATURES
• High current transfer ratio (CTR:MIN 600%)
• High input-to-output isolation voltage (3,750 Vrms)
• Ultra-miniature 4 pin SOP package
• High Load Voltage (Vceo = 300V MIN)
OPTIONS/SUFFIXES*
• -TR Tape and Reel
NOTE: Suffixes listed above are not included in marking on
device for part number identification.
