Notes:
1.
Maximum ratings are package dependent. The above ratings were determined using a Au-plated TO39 header without an encapsulant
for characterization. Ratings for other packages may differ. The junction temperature should be characterized in a specific package
to determine limitations. Assembly processing temperature must not exceed 325°C (< 5 seconds).
All products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled
and operated at 350 mA within the maximum ratings shown above. Efficiency decreases at higher currents. Typical values given are
within the range of average expected by manufacturer in large quantities and are provided for information only. All measurements
were made using a Au-plated TO39 header without an encapsulant. Optical characteristics measured in an integrating sphere using
Illuminance E.
Back contact metal is 80%/20% Au/Sn by weight, with target eutectic melting temperature of approximately 282°C.
Caution: To avoid leakage currents and achieve maximum output efficiency, die attach material must not contact the side of the
chip.
XB900 chips are shipped with the junction side up, requiring die transfer prior to die attach.
