SLR-50HL Series
NPN Photodarlington
Features
Narrow receiving angle
Spectrally matched to IRED
NPN planar epitaxial process
TO-18 hermetic dome lens package
Multiple sensitivity ranges
Extended temperature range
Description
The SLR-50HL series consists of an NPN silicon
planar
photodarlington
transistor
mounted
in
a
hermetically sealed TO-18 dome lens package. The
first stage base lead is connected to provide switching
control and circuitry biasing if needed. This series of
photodarlington devices is ideal in low irradiance
applications
where
higher
gain
is
needed.
The
hermetic package provides high reliability in hostile
environments. The various sensitivity ranges available
provide the desired output to meet multiple application
demands.
