Description
Flat Top Package
The HSDL-4400 Series of flat top
IR emitters use 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.
Applications
• Short Distance IR Links
• IrDA Compatible
• Small Handheld Devices
Pagers
Industrial Handhelds
• Diffuse LANs
• Wireless Audio
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 sub-
strate 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.

Notes:
1. IR Emitters have untinted, nondiffused lenses and IR Detectors have black tinted, nondiffused lenses.
2. Emitters and detectors are supplied in 12 mm embossed tape on 178 mm (7 inch) diameter reels, with 1500 units
per reel. Minimum order quantity and order increment are in quantity of reels only.
3. Emitters and detectors are supplied in bulk form in bags of 50 units.
4. The HSDL-44xx and HSDL-54xx families are not designed to be used in medical devices with life support functions
or in safety equipment (or similar applications where components failures would result in loss of life or physical
harm), eg. in automotive, medical or airline industries.

Package Dimensions
The following notes affect the
package outline drawings E
through I.
1. The pinout represents the
HSDL-54xx IR detectors where
the protruding support tab is
closest to the anode lead.
While the pinout is reversed
for the HSDL-44xx IR emitters
where the protruding support
tab is closest to the cathode
lead.
2. The protruding support tab of
the HSDL-54xx is connected
to the cathode lead. While the
protruding support tab of the
HSDL-44xx is connected to
the anode lead.
