Features
Wide range of collector currents.
Lens for high sensitivity.
Low cost plastic package.
Description
The LTR-209 consist of a NPN silicon phototransistor
mounted in a lensed, clear plastic, end looking package.
The lensing effect of the package allows an accep-
tance half angle of 8 measured from the optical axis
to the half power point. This series is mechanically and
spectrally matched to the LTE-209 series of infrared
emitting diodes.
