VISHAY
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 package.
