Silicon Phototransistor
SDP8406
DESCRIPTION
FEATURES
Side-looking plastic package
•
50¡ (nominal) acceptance angle
•
Wide sensitivity ranges
•
Mechanically and spectrally matched to
SEP8506 and SEP8706 infrared emitting diodes
•
The SDP8406 is an NPN silicon phototransistor molded
in a side-looking clear plastic package. The chip is
positioned to accept radiation through a plastic lens
from the side of the package.
