HFE4026 Low Drive Current Fiber Optic LED, Metal Package FEATURES • High speed 70 MHz • Optimized for linear optical output with drive currents between 5 and 60 mA • Metal TO-18 style package • High reliability • Power out designed for drive currents between 5 and 60 mA DESCRIPTION The HFE4026 is a high radiance GaAlAs 850 nanometer LED optimized for coupling into small fiber core diameters at a forward current of 5 to 60 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 HFE4026 is used at elevated temperatures, thermal resistance must be taken into consideration. APPLICATION The HFE4026 is a high radiance LED packaged on a TO-18 header with a metal can. Data rates can vary from DC to above 70 MHz depending upon component application. The LED is designed for use in fiber optic communications. As the current varies typically from 5 to 60 mA , the light intensity increases proportionally. Heat sinking is recommended to maintain the expected long life. If the HFE4026 is heat sinked, the package has a typical thermal resistance of per watt. If not heat sinked, typical thermal resistance is per watt. The HFE4026 LED is designed to give high fiber coupled power high radiance into a standard fiber optic cable . In order to enhance the light being sent into a fiber optic cable, a mm diameter glass microlens is placed over the "Caprock" junction. The microlens collimates the light, increasing the intensity directed toward a fiber optic cable. This creates a "SWEET SPOT" of power, allowing greater power to be launched into standard fiber optic cables.
