HFE4070 High Power Fiber Optic LED, Metal Package FEATURES • High power LED sends 115 µW into 100/140 micron fiber • High speed 85 MHz • Optimized for 50 mA operation • Designed to operate with Honeywell fiber optic receivers • Metal TO-18 type package • Metal TO-46 style package also available HFE4050 DESCRIPTION The HFE4070 is a high radiance AlGaAs 850 nanometer LED optimized for coupling into small fiber core diameters at a forward current of 50 mA. The patented "Caprock" LED chip is designed to combine high power coupling with wide bandwidth. The peak wavelength is matched for use with Honeywell silicon fiber optic detectors and receivers. When the HFE4070 is used at elevated temperatures, thermal resistance must be taken into consideration. APPLICATION The HFE4070 is a high radiance LED packaged on a TO-18 header with a metal can. Data rates can vary from DC to above 85 MHz depending upon component application. The LED is designed for use in fiber optic communications. As the current varies typically from 10 to 100 mA , the light intensity increases proportionally. Heat sinking is recommended to maintain the expected long life. If the HFE4070 is heat sinked the package has a typical thermal resistance of per watt. If not heat sinked, typical thermal resistance is per watt. The HFE4070 LED provides the maximum amount of radiance for the amount of forward current in the industry. A mm diameter glass microlens over the "Caprock" junction collimates the light, increasing the intensity. Thus, greater power is directed toward standard fiber optic cables.
