| Sanyo DL3149-070 Laser Diode Specifications The Sanyo DL3149-070 is a self-pulsation type index guided AlGaInP laser diode with a typical output of 685nm and an absolute maximum of 5mW. The diode features low threshold current which is achieved by a strained multi-quantum well active layer. The DL3149-070 is suitable for applications including optical disc systems, measurement systems, and other products where low noise and reduced speckle is desirable. The DL3149-070 has a 5.6mm package. 2 LD PD 1 3 Internal Circuit Absolute Maximum Ratings (Tc=25 C) Characteristic Symbol Value Unit Optical output power Laser diode reverse voltage Photodiode reverse voltage Operating temperature Storage temperature Po VR(LD) VR(PD) Topr Tstg 5 2 30 10 to +60 40 to +85 mW V V O5.6mm 123 2 C C 1 3 Package Type: O5.6mm Operating and Electrical Characteristics (Tc=25 C) Characteristic Symbol Min.
