Notes :
(1) Tolerance : VF :±0.1V, IV :±7%, W_d :±0.5nm
(2) The luminous intensity IV was measured at the peak of the spatial pattern which may not be
aligned with the mechanical axis of the LED package.
(3) Θ_1/2 is the off-axis where the luminous intensity is 1/2 of the peak intensity
(4) Thermal resistance = Rth JA : Junction/ambient , Rth JS : Junction/solder point
Pad design for improved heat dissipation : Cu-area > Cu 16mm2 per pad, FR4, t=1.6mm
(5) Not designed for reverse operation
