Description
The LTS-540A, LTD-5000, LTC-5000 series are 0.52 inch (13.2mm) height 7-Segment displays. AlGaAs red Bright red
, yellow and red orange displays have gray face and white segments. Green displays have gray face and green segments.
High efficiency red displays have red face and red segments.
The AlGaAs red seven segment displys are designed for applications requiring low power consumption. They are
tested and selected for their excellent low current characteristics to ensure that the segments are matched at low current.
Drive current as low as 1 mA per segment is available.
The AlGaAs red series devices utilize LED chips which are made from AlGaAs on a non-transparent GaAs substrate.
The bright red and green series devices utilize LED chips which are made from GaP on a transparent GaPsubstrate. The
yellow and red orange series devices utilize LED chips which are made from GaAsP on a transparent GaP substrate.
