description
The CLE335 is an advanced, high
efficiency, high speed, AlGaAs
infrared-emitting diode. Output
power typically exceeds standard
AlGaAs emitters by 50%. The
TO-46 header provides the thermal
environment for reliable operation
over an extremely wide temperature
range. The lens is designed to
provide a highly collimated radiation
pattern from 0.10" to 0.20" from the
lens tip. Call Clairex for assistance.

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. Derate linearly 0.64mA/C from 25C free air temperature to T
A
=+150C.
4. 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.
5. Derate linearly 1.4mW/C from 25C free air temperature to T
A
= +150C.
Clairex reserves the right to make changes at any time to improve design and to provide the best possible product.

is a measure of irradiance (power/unit area) within a 0.444" (1.128cm) diameter area, centered on the
mechanical axis of the device and spaced 2.54" (6.45cm) from the lens side on the tab. This is geometrically
equivalent to a 10 cone.
