description 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 pro- ducing high light output over a wide range of drive currents and temperature. features subminiature flat top and dome package size ?2x2 mm ir emitter 875 nm ts algaas intensity ?17 mw/sr speed ?40 ns wide range of drive currents 500 a to 500 ma ir detector pin photodiode high sensitivity speed ?7.5 ns flexible lead configurations surface mount or through hole applications short distance ir links irda compatible small handheld devices pagers industrial handhelds diffuse lans wireless audio hsdl-44xx ir emitter series hsdl-54xx ir detector series high-performance ir emitter and ir pin photodiode in subminiature smt package data sheet
