Selection Guide
Notes:
1. θ1/2 is the angle from optical centerline where the luminous intensity is 1/2 of the optical peak value.
2. Luminous intensity/ luminous Flux: +/-15%.
3. Luminous intensity value is traceable to CIE127-2007 standards.
Absolute Maximum Ratings at TA=25°C
Electrical / Optical Characteristics at TA=25°C
Notes:
1.Wavelength: +/-1nm.
2.Forward Voltage: +/-0.1V.
3.Wavelength value is traceable to CIE127-2007 standards.
4.Excess driving current and/or operating temperature higher than recommended conditions may result in severe light degradation or
premature failure.
Notes:
1. 1/10 Duty Cycle, 0.1ms Pulse Width.
2. 2mm below package base.
3. 5mm below package base.
4. Relative humidity levels maintained between 40% and 60% in production area are recommended to avoid the build-up of static
electricity – Ref JEDEC/JESD625-A and JEDEC/J-STD-033.
