ELECTRIC
FEATURES
ML4xx26 series is AlGaAs laser diodes which
provide a stable, single transverse mode ocillation
with emission wavelength of 785nm and standard
continuous light output of 5mW.
ML4xx26 are hermetically sealed devices having
the photodiode for optical output monitoring.
ML4xx26 is produced by the MOCVD crystal
growth method which is excellent in mass production
and characteristics uniformity.
Note 2: Applicable to ML44126R and ML44126N
Note 3: RL=the load resistance of photodiode
ABSOLUTE MAXIMUM RATINGS (Note 1)
Note1: The maximum rating means the limitation over which the laser should not be operated even instant time,
and this does not mean the guarantee of its lifetime.As for the reliability,please refer to the reliability report from Mitsubishi
Semiconductor Quality Assurance Department.
