Description
These 10-element LED arrays are
designed to display information
in easily recognizable bar graph
form. The packages are end
stackable and therefore capable
of displaying long strings of
information. Use of these bar
graph arrays eliminates the
alignment, intensity, and color
matching problems associated
with discrete LEDs. The HDSP-
4820/4830/4840/4850 and HLCP-
J100 each contain LEDs of one
color. The HDSP-4832/4836 are
multicolor arrays with High
Efficiency Red, Yellow, and High
Performance Green LEDs in a
single package.

Notes:
1. The bar graph arrays are categorized for luminous intensity. The category is designated by a letter located on the side of the
package.
2. The dominant wavelength, λd, is derived from the CIE chromaticity diagram and is that single wavelength which defines the color of
the device.
3. The HDSP-4832/-4836/-4840/-4850 bar graph arrays are categorized by dominant wavelength with the category designated by a
number adjacent to the intensity category letter. Only the yellow elements of the HDSP-4832/-4836 are categorized for color.
4. Electrical/optical characteristics of the High-Efficiency Red elements of the HDSP-4832/-4836 are identical to the HDSP-4830
characteristics. Characteristics of Yellow elements of the HDSP-4832/-4836 are identical to the HDSP-4840. Characteristics of
Green elements of the HDSP-4832/-4836 are identical to the HDSP-4850.
5. Reverse voltage per LED should be limited to 3.0 V max. for the HDSP-4820/-4830/-4840/-4850/-4832/-4836 and 5.0 V max. for
the HLCP-J100.

Electrical/Optical
These versatile bar graph arrays
are composed of ten light emit-
ting diodes. The light from each
LED is optically stretched to form
individual elements. The Red
(HDSP-4820) bar graph array
LEDs use a p-n junction diffused
into a GaAsP epitaxial layer on a
GaAs substrate. The AlGaAs Red
(HLCP-J100) bar graph array
LEDs use double heterojunction
AlGaAs on a GaAs substrate. HER
(HDSP-4830) and Yellow (HDSP-
4840) bar graph array LEDs use
a GaAsP epitaxial layer on a GaP
substrate. Green (HDSP-4850)
bar graph array LEDs use liquid
phase GaP epitaxial layer on a
GaP substrate. The multicolor bar
graph arrays (HDSP-4832/4836)
have HER, Yellow, and Green
LEDs in one package.
These displays are designed for
strobed operation. The typical
forward voltage values can be
scaled from Figures 5 and 11.
These values should be used to
calculate the current limiting
resistor value and typical power
consumption. Expected maxi-
mum VF values for driver circuit
design and maximum power
dissipation may be calculated
using the VFMAX models:
Standard Red HDSP-4820 series
VFMAX = 1.8 V + IPeak (10 Ω)
For: IPeak ≥ 5 mA
AlGaAs Red HLCP-J100 series
VFMAX = 1.8 V + IPeak (20 Ω)
For: IPeak ≤ 20 mA
VFMAX = 2.0 V + IPeak (10 Ω)
For: IPeak ≥ 20 mA
HER (HDSP-4830) and Yellow
(HDSP-4840) series
VFMAX = 1.6 + I Peak (45 Ω)
For: 5 mA ≤ IPeak ≤ 20 mA
VFMAX = 1.75 + IPeak (38 Ω)
For: IPeak ≥ 20 mA
Green (HDSP-4850) series
VFMAX = 2.0 + I Peak (50 Ω)
For: IPeak > 5 mA
Figures 4 and 10 allow the
designer to calculate the
luminous intensity at different
peak and average currents. The
following equation calculates
intensity at different peak and
average currents:
IVAVG = (IFAVG/IFAVG DATA
SHEET)ηpeak)(IVDATA
SHEET)
Where:
IVAVG is the calculated time
averaged luminous intensity
resulting from IFAVG.
IFAVG is the desired time
averaged LED current.
IFAVG DATA SHEET is the data
sheet test current for IVDATA
SHEET.
ηpeak is the relative efficiency at
the peak current, scaled from
Figure 4 or 10.
IV DATA SHEET is the data sheet
luminous intensity, resulting
from IFAVG DATA SHEET.
For example, what is the
luminous intensity of an HDSP-
4830 driven at 50 mA peak 1/5
duty factor?
IFAVG = (50 mA)(0.2) = 10 mA
IFAVG DATA SHEET = 10 mA
ηpeak = 1.3
IV DATA SHEET = 3500 µcd
Therefore
IVAVG = (10 mA/10 mA)
(1.3)(3500 µcd)
= 4550 µcd
