description
The CLE435 is an advanced,
high-efficiency, high speed, AlGaAs
light emitting diode. 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 applications
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 0.60mA/C from 25C free air temperature to T
A
= +125C.
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 2.0mW/C from 25C free air temperature to T
A
= +125C.
Clairex reserves the right to make changes at any time to improve design and to provide the best possible product.

e
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 of the tab. This is geometrically
equivalent to a 10 cone.
2. Other ranges of power output and test conditions can be specified. Call Clairex for applications assistance.
