| HL6315/16G AlGaInP Laser Diodes Description The HL6315/16G are 0.63 m band AlGaInP laser diodes with a multi-quantum well (MQW) structure. They are suitable as light sources for laser pointers and optical equipment. Application * Laser pointer Features * * * * Visible light output: 635 nm Typ (nearly equal to He-Ne Gas Laser) Optical output power: 3 mW CW Low Operating current: 30mA Typ Low Operating voltage: 2.7 V Max 111 HL6315/16G Absolute Maximum Ratings (TC = 25C) Item Optical output power Pulse optical output power LD reverse voltage PD reverse voltage Operating temperature Storage temperature Note: Symbol PO PO (pulse) VR (LD) VR (PD) Topr Tstg Rated Value 3 5* 2 30 -10 to +50 -40 to +85 1 Unit mW mW V V C C 1.
