Notes:
1. Maximum I_PEAK at f = 1 kHz, DF = 6.7%.
2. Refer to Figure 6 to establish pulsed operating conditions.
3. Derate linerally as shown in Figure 5.
4. The transient peak current is the maximum non-recurring peak current the device can withstand without damaging the LED die and
is not recommended that the device be operated at peak currents beyond the Absolute Maximum Peak Forward Current.

Notes:
1. The dominant wavelength, λ_d, is derived from the CIE chromaticity diagram and represents the color of the device.
2. The radiant intensity, Ie, in watts per steradian, may be found from the equation Ie = Iv/_ηv, where Iv is the luminous intensity in candelas and ηv is
luminous efficacy in lumens/watt.
3. The approximate total luminous flux output within a cone angle of 2θ about the optical axis, φ_v(2θ), may be obtained from the following formula:
φ_v(2θ) = [φ_v(θ)/Iv(0)]Iv; Where: φ_v(θ)/Iv(0) is obtained from Figure 7.
