SLR-50HF Series
NPN Photodarlington
Features
Wide receiving angle
TO-18 hermetic flat window
Multiple sensitivity ranges
Extended temperature range
Description
The SLR-50HF series consists of an NPN silicon
planar photodarlington transistor mounted in a
hermetically sealed TO-18 flat window package. The
wide
angle
of
receiving
sensitivity
provides
a
relatively uniform output over a wide field of view.
The first stage base lead is connected for those
applications where switching control and circuitry
biasing is needed. 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.
