Units Test Conditions Forward Voltage VF . .4 V IF = 0 mA Reverse Voltage VR 5 IR = 100 µA Capacitance C 40 pF VF = 0, f = 1 MHz Thermal Resistance RθJ-PIN 40 ˚C/W LED Junction-to-Cathode Lead Dominant Wavelength [1] λd 6 630 634 nm IF = 0 mA Peak Wavelength λp 639 nm Peak of Wavelength of Spectral Distribution at IF = 0 mA Spectral Halfwidth ∆λ1/ 17 nm Wavelength Width at Spectral Distribution 1/ Power Point at IF = 0 mA Luminous Efficacy [] ηv 155 lm/W Emitted luminous power/ Emitted radiant power Luminous Flux jV 1300 mlm IF = 0 mA Luminous Efficiency [3] ηe 30 lm/W Luminous Flux/Electrical Power IF = 0 mA Notes: 1. The dominant wavelength is derived from the Chromaticity Diagram and represents the color of the lamp. . 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 the luminous efficacy in lumens/watt. 3. ηe = jV / IF x VF , where jV is the emitted luminous flux, IF is electrical forward current and VF is the forward voltage.
