description
The CLE331E is an advanced, high
efficiency, high speed, point source,
AlGaAs infrared-emitting diode
intended for applications requiring a
uniform output radiation pattern. The
point source die junction is typically
0.002" dia. and provides a uniform
radiation pattern without the usual
bond wire shadow effect. The TO-46
header provides the thermal
environment for reliable operation
over a wide temperature range.

notes:
1. Maximum operating temperature of the metallurgical junction.
2. 0.06" (1.5mm) from the header for 5 seconds maximum. Maximum
temperature can be 260C if wave soldering.
3. Pulsed condition only. Maximum pulse width is 2.0
s at 2% duty cycle. Use
good judgement when operating this device under these conditions. Thermal
transients exceeding these restrictions can cause irreversible damage.
4. Derate linearly 2.66mW/C from 25C free air temperature to T
