Agilent High-Performance IR Emitter
and IR PIN Photodiode in
Subminiature SMT Package
Data Sheet
HSDL-44xx IR Emitter Series
HSDL-54xx IR Detector Series
Flat Top Package
The HSDL-4400 Series of flat top
IR emitters uses an untinted,
nondiffused, truncated lens to
provide a wide radiation pattern
that is useful for short distance
communication where alignment
of the emitter and detector is not
critical. The HSDL-5400 Series of
flat top IR detectors uses the
same truncated lens design as
the HSDL-4400 Series of IR
emitters with the added feature
of a black tint that acts as an
optical filter to reduce the
effects of ambient light, such as
sun, incandescent and
fluorescent light from interfering
with the IR signal.
Dome Package
The HSDL-4420 Series of dome
IR emitters uses an untinted,
nondiffused lens to provide a 24
degree viewing angle with high
on-axis intensity. The
HSDL-5420 Series of IR
detectors uses the same lens
design as the HSDL-4420 IR
emitter and optical filter used in
the HSDL-5400 IR detector.
Lead Configuration
All of these devices are made by
encapsulating LED and PIN
photodiode chips on axial lead
frames to form molded epoxy
subminiature packages. A
variety of lead configurations is
available and includes: surface
mount gull wing, yoke lead, or
Z-bend and through hole lead
bends at 2.54 mm (0.100 inch)
center spacing.
Technology
The subminiature solid state
emitters utilize a highly
optimized LED material,
transparent substrate aluminum
gallium arsenide, TS AlGaAs.
This material has a very high
radiant efficiency, capable of
producing high light output over
a wide range of drive currents
and temperature.
