MITSUBISHI LASER DIODES ML7xx19 SERIES Notice: Some parametric limits are subject to change. TYPE NAME 1310nm InGaAsP FP LASER DIODES ML720J19S, ML720K19S, ML728C19S ML725B19F, ML725C19F DESCRIPTION FEATURES ML7XX19 series are InGaAsP laser diodes which provide a stable, single transverse mode oscillation with emission wavelength of 1310nm and standard continuous light output of 5mW. ML7XX19 are hermetically sealed devices having the photo diode for optical output monitoring. This is suitable for such applications as the light sources for optical communication systems up to 2.5Gbps transmission applications. •1310nm typical emission wavelength, FP-LDs •Wide temperature range operation(-40 to 85ºC) •φ5.6mm TO-CA N package Flat window cap : ML720J19S, ML725B19F Ball lens cap : ML720K19S, ML725C19F •φ3.8mm TO-CA N package Ball lens cap : ML728C19S APPLICATION •Optical communication system ABSOLUTE MAXIMUM RATINGS Symbol Po VRL VRD IFD Tc Tstg Parameter Light output power Laser reverse voltage PD reverse voltage PD forward current Operation temperature Storage temperature Conditions CW - Ratings 10[7] 2 20 2 -40 to +85 -40 to +100 Unit mW V V mA ºC ºC ELECTRICAL/OPTICAL CHARACTERISTICS(Tc=25oC) Symbol Parameter Ith Iop Vop η λc ∆λ θ// Threshold current Operation current Operating voltage Slope efficiency Center wavelength Spectral Width Beam divergence angle(parallel) Beam divergence angle (perpendicular) Rise and Fall time (20%-80%) Monitor Current (PD) Dark Current (PD) Capacitance (PD) θ⊥ tr,tf Im Id Ct Pf <2> Df <2> Fiber Coupling characteristics at peak coupling <3> Test Conditions Min.
