Data Sheet

Application Precautions



The drive current of the LED must not exceed the

maximum allowable limit across temperature as stated in

the data sheet. Constant current driving is recommended

to ensure consistent performance.



Circuit design must cater for the entire range of forward

voltage (VF) of the LEDs to ensure that the intended drive

current can always be achieved.



If the LED is to be used with an LED of another color to

achieve color mixing, Broadcom does not guarantee the

consistency of the resultant color. Contact a Broadcom

sales representative for these applications.



The LED exhibits slightly different characteristics at

different drive currents, which might result in larger

variation of its performance (for example, intensity,

wavelength, and forward voltage). Set the application

current as close as possible to the test current to minimize

these variations.



The LED is not intended for reverse bias. Use other

appropriate components for such purposes. When driving

the LED in matrix form, ensure that the reverse bias voltage

does not exceed the allowable limit of the LED.



Avoid rapid change in ambient temperatures, especially in

high-humidity environments, because they cause

condensation on the LED.



If the LED is to be used in harsh environments, protect the

LED against damages caused by rain water, dust, oil,

corrosive gases, external mechanical stress, and so on.

Eye Safety Precautions

LEDs may pose optical hazards when in operation. Do not look

directly at operating LEDs because it might be harmful to the

eyes. For safety reasons, use appropriate shielding or personal

protection equipment.
