MITSUBISHI LASER DIODES ML4XX26 SERIES FOR OPTICAL INFORMATION SYSTEMS TYPE NAME ML40126N ML44126N,ML44126R FEATURES FEATURES • Output 5mW(CW) • Built-in monitor photodiode • Low droop 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. APPLICATION • Laser Beam Printing, Digital Copy ABSOLUTE MAXIMUM RATINGS (Note 1) Symbol Po Parameter Conditions Ratings Unit CW 8 mW Light output power VRL Reverse voltage (laser diode) - 2 V VRD Reverse voltage (Photodiode) - 30 V IFD Forward current (Photodiode) - 10 mA Tc Case temperature - -40~ +60 °C Storage temperature - -40~ +100 °C Tstg 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.
