Description
These low current seven segment
displays are designed for applica-
tions requiring low power
consumption. They are tested and
selected for their excellent low
current characteristics to ensure
that the segments are matched at
low currents. Drive currents as
low as 1 mA per segment are
available.
Pin for pin equivalent displays
are also available in a standard
current or high light ambient
design. The standard current
displays are available in all colors
and are ideal for most applica-
tions. The high light ambient
displays are ideal for sunlight
ambients or long string lengths.

Notes:
1. Device case temperature is 25°C prior to the intensity measurement.
2. The digits are categorized for luminous intensity. The intensity category is designated by a letter on the side of the package.
3. The dominant wavelength, λd, is derived from the CIE chromaticity diagram and is the single wavelength which defines the color of the
device.
4. Typical specification for reference only. Do not exceed absolute maximum ratings.
5. The yellow (HDSP-A800) and Green (HDSP-A900) displays are categorized for dominant wavelength. The category is designated by a
number adjacent to the luminous intensity category letter.

Soldering/Cleaning
Cleaning agents from the ketone
family (acetone, methyl ethyl
ketone, etc.) and from the
chorinated hydrocarbon family
(methylene chloride, trichloro-
ethylene, carbon tetrachloride,
etc.) are not recommended for
cleaning LED parts. All of these
various solvents attack or
dissolve the encapsulating
epoxies used to form the package
of plastic LED parts.
For information on soldering
LEDs please refer to Application
Note 1027.
