Data Sheet
Cree’sTR3547LEDsarethenextgenerationofsolid-stateLEDemittersthatcombinehighlyefcientInGaNmaterials
withCree’sproprietarydevicetechnologyandsilicon-carbidesubstratestodeliversuperiorvaluefortheTV-backlighting
andgeneral-illuminationmarkets.TheTR3547LEDsareamongthebrightestinthetop-viewmarketwhiledeliveringa
lowforwardvoltage,resultinginaverybrightandhighlyefcientsolution.Thedesignisoptimallysuitedforindustry-
standardtop-viewpackages.

Notes:
1. Maximum ratings are package-dependent. The above ratings were determined using a Cree SMT package (with silicone
encapsulation) for characterization. Ratings for other packages may differ. Junction temperature should be characterized in a
specicpackagetodeterminelimitations.Assemblyprocessingtemperaturemustnotexceed325°C(<5seconds).
2. Productresistancetoelectrostaticdischarge(ESD)accordingtotheHBMismeasuredbysimulatingESDusingarapidavalanche
energytest(RAET).TheRAETproceduresaredesignedtoapproximatethemaximumESDratingsshown.
3. Allproductsconformtothelistedminimumandmaximumspecicationsforelectricalandopticalcharacteristicswhenassembled
andoperatedat50mAwithinthemaximumratingsshownabove.Efciencydecreasesathighercurrents.Typicalvaluesgiven
arewithinthe rangeofaveragevaluesexpectedbymanufacturerinlargequantitiesandareprovidedforinformationonly.All
measurementsweremadeusinglampsinT-13/4packages(withHysolOS4000epoxyencapsulantandsiliconedieattach).Optical
characteristicsmeasuredinanintegratingsphereusingIlluminanceE.
