See Figure 2 to establish pulsed operating conditions. 2. For Red and Green series derate linearly from 50C at 0.5 mA/C. For Yellow series derate linearly from 50C at 0.2 mA/C. 3. The transient peak current is the maximum non-recurring peak current the devices can withstand without damaging the LED die and wire bonds. It is not recommended that the device be operated at peak currents beyond the Absolute Maximum Peak Forward Current. 3 Electrical/Optical Characteristics at TA = 25C Symbol PEAK Description T-13/4 T-13/4 Low Dome T-1 Min.

The dominant wavelength, d, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device. 2. The radiant intensity, Ie , in watts per steradian, may be found from the equation Ie = IV/V, where IV is the luminous intensity in candelas and V is the luminous efficacy in lumens/watt. 4 Red, Yellow, and Green 1.0 RELATIVE INTENSITY EMERALD GREEN TA = 25 C GREEN HIGH EFFICIENCY RED 0.5 YELLOW 0 500 550 600 650 700 750 WAVELENGTH - nm Figure 1.
