ML120G3

ML1XX3 SERIES FOR OPTICAL INFORMATION SYSTEMS TYPE NAME ML1013R, ML1413R, ML120G3 FEATURES • High Power: 50mW (CW), 60mW (pulse) Light: 685nm (typ) DESCRIPTION ML1XX3 is a high power AlGaInP semiconductor laser which provides a stable, single transverse mode oscillation with emission wavelength of 685-nm and standard CW light output of 50mW. ML1XX3 has a window-mirror-facet which improves the maximum output power. That leads to highly reliable and high-power operation. • Visible APPLICATION Optical disc drive (High Density / High Speed) ABSOLUTE MAXIMUM RATINGS (Note 1) Symbol Po VRL VRD IFD Tc Tstg Parameter Light output power Reverse voltage (laser diode) Reverse voltage (Photodiode) Forward current (Photodiode) Case temperature Storage temperature Conditions CW Pulse(Note 2) Ratings 60 60 2 30 10 -10~ +60 -40~ +100 mW V V mA °C °C Unit 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.
