NOTES:
1. Dimensions for all drawings are in inches (mm).
2. Lead spacing is measured where the leads emerge from
the package.
3. Protruded resin under the flange is 0.059" (1.5 mm) max.
4. All tolerances are 0.10" (0.25 mm) unless otherwise
specified.
APPLICATIONS
Exterior automotive lighting
Area displays
Backlighting
Message panels
FEATURES
AllnGaP (Aluminum Indium Gallium Phosphide) technology
High current application
Reduced thermal resistance
Tube packaging
DESCRIPTION
This low profile, 4-pin LED provides a more uniform and
evenly distributed illumination than existing LED designs. Its
unique optical package enables designers to utilize fewer LEDs
while achieving superior lighting performance.
