SLT-50HF Series
NPN Phototransistor
Features
Wide receiving angle
NPN planar epitaxial process
Multiple sensitivity ranges
Extended temperature range
Hermetic TO-18 case with flat window
Description
The SLT-50HF series consists of an NPN silicon
planar
epitaxial
phototransistor
mounted
in
a
hermetically sealed TO-18 flat window package. The
wide angle of receiving sensitivity provides a relatively
uniform response over a wide field of view. The TO-18
hermetic package provides high reliability in hostile
environments. The various sensitivity ranges available
provide the desired output to meet multiple application
demands.
