description
The CLE539 contains a GaN,
high power output, blue LED
bonded to a ceramic substrate and
mounted on a TO-46 header. A
phosphor coating is applied to the
die which, when excited, emits
white light. The TO-46 header
provides the thermal environment
for reliable operation over a wide
temperature range. For additional
information, call Clairex.
notes:
1. 0.06” (1.5mm) from the header for 5 seconds maximum.
2. Derate linearly 0.44mA/°C from 25°C free air temperature to TA = +125°C.
3. Derate linearly 1.60mW/°C from 25°C free air temperature to TA = +125°C.
