Silicon Photodarlington
SDP8105
DESCRIPTION
FEATURES
T-1 plastic package
•
20¡ (nominal) acceptance angle
•
Consistent optical properties
•
Mechanically and spectrally matched to
SEP8505 and SEP8705 infrared emitting diodes
•
The SDP8105 is an NPN silicon photodarlington
transfer molded in a T-1 black plastic package to
minimize effect of visible ambient light. Transfer molding
of this device assures superior optical centerline
performance compared to other molding processes.
Lead lengths are staggered to provide a simple method
of polarity identification.
