Notes:
4. The displays are categorized for luminous intensity with the intensity category designated by a letter on the left hand side of the
package. The luminous intensity minimum and categories are determined by computing the numerical average of the individual dot
intensities.
5. The dominant wavelength is derived from the C.I.E. Chromaticity diagram and is that single wavelength which defines the color of the
device.
6. Typical specification for reference only. Do not exceed absolute maximum ratings.
7. The displays are categorized for dominant wavelength with the category designated by a number adjacent to the intensity category
letter.

Operational Considerations
Electrical Description
These display devices are composed of light emitting diodes, with
the light from each LED optically
stretched to form individual dots.
These display devices are well
suited for strobed operation. The
typical forward voltage values can
be scaled from Figure 2. These
values should be used to calculate
the current limiting resistor value
and the typical power dissipation.
Expected maximum VF values, for
driver circuit design and maximum
power dissipation, may be
calculated using the following
VFMAX models:
IVAVG is the calculated time
averaged luminous intensity
resulting from IFAVG.
For example, what is the luminous
intensity of an AlGaAs Red (HDSPL10X) driven at 50 mA peak 1/5
duty factor?
IFAVG = 50 mA * 0.2 = 10 mA
IFAVG DATA SHEET = 2 mA
ηPEAK = 0.98
IV DATA SHEET = 1650 µcd
Therefore
IVAVG = (10 mA/2 mA)(0.98)
(1650 µcd) = 8085 µcd
Thermal Considerations
AlGaAs Red
(HDSP-M10x):
VFMAX = 1.8 V + IPEAK(20 Ω)
For IPEAK ≤ 20 mA
VFMAX = 2.0 V + IPEAK(10 Ω)
For IPEAK ≥ 20 mA
HER (HDSP-450x):
VFMAX = 1.75 V + IPEAK(35 Ω)
For IPEAK ≥ 5 mA
Green (HDSP-510x):
VFMAX = 1.75 V + IPEAK(38 Ω)
For IPEAK ≥ 5 mA
Figure 3 allows 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)(IV DATA SHEET)
Where:
IFAVG is the desired time averaged
LED current.
IFAVG DATA SHEET is the time
averaged data sheet test current
for IVDATA SHEET.
ηPEAK is the relative efficiency at
the peak current, scaled from
Figure 3.
IV DATA SHEET is the time
averaged data sheet luminous
intensity, resulting from IFAVG
DATA SHEET.
The device thermal resistance may
be used to calculate the junction
temperature of the central LED.
The equation below calculates the
junction temperature of the central
(hottest) LED.
TJ = TA + (PD)(RθJ-A)(N)
PD = (VFMAX)(IFAVG)
RθJ-A = RθJ-PIN+ RθPIN-A
TJ is the junction temperature of
the central LED.
TA is the ambient temperature.
PD is the power dissipated by one
LED.
N is the number of LEDs ON per
character.
VFMAX is calculated using the
appropriate VF model.
RθJ-A is the package thermal
resistance from the central LED
to the ambient.
RθJ-PIN is the package thermal
resistance from the central LED
to pin.
RθPIN-A is the package thermal
resistance from the pin to the
ambient.
For example, what is the maximum
ambient temperature an HDSPL10X can operate with the
following conditions:
IPEAK = 125 mA
IFAVG = 10 mA
RθJ-A = 50°C/W
N = 35
TJMAX = 110°C
VFMAX = 2.0 V + (0.125 A)(10)
= 3.25 V
PD = (3.25 V)(0.01 A)
= 0.0325 W
TA = 110°C –
(50°C/W)(0.0325 W)(35)
= 53°C
The maximum number of dots ON
for the ASCII character set is 20.
What is the maximum ambient
temperature an HDSP-L10X can
operate with the following
conditions:
IPEAK = 125 mA
IFAVG = 10 mA
RθJ-A = 50°C/W
N = 20
TJMAX = 110°C
VFMAX = 3.25 V
PD = 0.0325 W
TA = 110°C –
(50°C/W)(0.0325 W)(20)
= 77°C
Therefore, the maximum ambient
temperature can be increased by
reducing the average number of
dots ON from 35 to 20 dots ON per
display.
