DESCRIPTION

· The HSDL-4400 Series features flat top IR emitters with an untinted, nondiffused, truncated lens for wide radiation patterns, ideal for short-distance communication where alignment is not critical.

· The HSDL-5400 Series includes flat top IR detectors with a similar lens design as the HSDL-4400, enhanced with a black tint to filter ambient light and improve IR signal clarity.

· The HSDL-4420 Series offers dome IR emitters with an untinted, nondiffused lens, providing a 24-degree viewing angle and high on-axis intensity.

· The HSDL-5420 Series IR detectors use the same lens design as the HSDL-4420, combined with the optical filter from the HSDL-5400.

FEATURES

· Subminiature flat top and dome package size: 2x2 mm.

· IR emitter operates at 875 nm using TS AlGaAs technology, with an intensity of 17 mW/sr and a speed of 40 ns.

· Supports a wide range of drive currents from 500 µA to 500 mA.

· IR detector features a PIN photodiode with high sensitivity and a speed of 7.5 ns.

· Available in flexible lead configurations including surface mount or through hole options.

APPLICATIONS

· Suitable for short distance IR links and IrDA compatible devices.

· Ideal for small handheld devices such as pagers and industrial handhelds.

· Used in diffuse LANs and wireless audio systems.

· Applicable in the HSDL-44xx IR Emitter Series and HSDL-54xx IR Detector Series for high-performance IR communication in subminiature SMT packages.
