High power output

description

The CLE234E is an advanced, high

efficiency, high speed AlGaAs

infrared-emitting diode with four times

the emitting surface of the typical

AlGaAs emitter. High power output is

achieved with four equally spaced

cathode contacts for higher current

distribution. Cathode contacts are

bonded in pairs, each pair bonded to

a separate lead, which need to be

connected during operation. Chip

size is 0.030” by 0.030”. The TO-46

header provides reliable operation

over a wide temperature range.

Operation at this level requires a proper heat sink.

Clairex reserves the right to make changes at any time to improve design and to provide the best possible product.
