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.
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.
FEATURES
• AllnGaP (Aluminum Indium Gallium Phosphide) technology
• High current application
• Reduced thermal resistance
• Tube packaging
APPLICATIONS
• Exterior automotive lighting
• Area displays
• Backlighting
• Message panels
