LUXEON III Star DS46 (3/06)
1.Lumileds maintains a tolerance of ± 0.06V on forward voltage measurements.
2.Dynamic resistance is the inverse of the slope in linear forward voltage model for LEDs. See Figures 3a and 3b.
3.Measured between 25
1.Proper current derating must be observed to maintain junction temperature below the maximum. For more
2.Allowable board temperature to avoid exceeding maximum junction temperature at maximum Vf limit at 700 mA based on
3.LEDs are not designed to be driven in reverse bias. Please consult Lumileds' Application Brief AB11 for further information.
