High Intensity LED,

∅ 3 mm Tinted Diffused

Description

This LED contains the double heterojunction (DH)

GaAlAs on GaAs technology.

This deep red LED can be utilized over a wide range

of drive current. It can be DC or pulse driven to

achieve desired light output.

The device is available in a 3 mm tinted diffused pack-

age.
