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
specicpackagetodeterminelimitations.Assemblyprocessingtemperaturemustnotexceed325°C(<5seconds).
