Notes
:
1. Derate linerally as shown in Figure 4.
2. Refer to Figure 5 to establish pulsed operating conditions.
3. The transient peak current is the maximum non-recurring peak current the device can
withstand without damaging the LED die and wire bonds.
4. Drive currents between 5 mA and 30 mA are recommended for best long term
performance.
5. Operation at currents below 5 mA is not recommended, please contact your Hewlett-
Packard sales representative.

Notes:
1. The dominant wavelength,
λ
, is derived from the CIE Chromaticity Diagram and represents the color of the device.
2.
θ
1/2
is the off-axis angle where the luminous intensity is 1/2 the peak intensity.
