Notes:
1. These displays are recommended for high ambient light operation. Please refer to the HDSP-N10X AlGaAs data sheet for low current
operation.
2. Universal pinout brings the anode and cathode of each segment's LED out to separate pins. See internal diagram E.

Description
The 20 mm (0.8 inch) LED seven
segment displays are designed
for viewing distances up to 10
metres (33 feet). These devices
use an industry standard size
package and pinout. All devices
are available as either common
anode or common cathode.
These displays are ideal for most
applications. Pin for pin
equivalent displays are also
available in a low current design.
The low current displays are ideal
for portable applications. For

Notes:
1. Case temperature of the device immediately prior to the intensity measurement is 25
°
C.
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,
λ
d
, is derived from the CIE chromaticity diagram and is that single wavelength which defines the color of
the device.
4. Typical specification for reference only. Do not exceed absolute maximum ratings.
5. For low current operation, the AlGaAs Red HDSP-N100 series displays are recommended. They are tested at 1 mA dc/segment and
are pin for pin compatible with the HDSP-N150 series.
6. The Yellow (HDSP-4200) and Green (HDSP-8600) displays are categorized for dominant wavelength. The category is designated by
a number adjacent to the luminous intensity category letter.

For information on contrast
enhancement please see
Soldering/Cleaning
Cleaning agents from the ketone
family (acetone, methyl ethyl
ketone, etc.) and from the
chlorinated 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.
