Characteristic Symbol Test Condition Min Typ Max Unit
Forward voltage VF I
F= 20mA - 2.1 2.5 V
*4Luminous intensity IV IF= 20mA 80 160 - mcd
*5Peak wavelength λP IF= 20mA - 570 - nm
Spectrum bandwidth ∆λ IF= 20mA - 30 - nm
Reverse current IR V
R=4V - - 10 uA
*3Half angle θ1/2 IF= 20mA - ±22 - deg
*3. θ1/2 is the off-axis angle where the luminous intensity is 1/2 the peak intensity
*4. Luminous intensity maximum tolerance for each grade classification limit is ±18%
*5. Dominant wavelength is derived form the CIE1931 Chromaticity diagram
A tolerance of ±0.5nm for dominant wavelength
