DL-3147-021
Index Guided AlGaInP Laser Diode
Overview
DL-3147-021 is index guided 645 nm (Typ.) AlGaInP laser diode with low
threshold current. The low threshold current is achieved by a strained
multiple quantum well active layer. DL-3147-021 is suitable for laser
pointer.
Features
• Short wavelength : 645 nm (Typ.)
• Low threshold current : Ith = 30 mA (Typ.)
• Low operating voltage : Vop = 2.3 V (Typ.)
• Small package : 5.6 mm ø
