Product Overview
The IR15-21C_TR8 is an EVERLIGHT infrared emitting diode built with GaAlAs chip material. The device is provided as a 1206 miniature top-view flat SMD package with a water clear plastic mold and water clear lens color, making it suited to compact surface-mount infrared emitter layouts.
At IF=20 mA and Ta=25°C, the diode has a typical peak wavelength of 940 nm, typical spectral bandwidth of 45 nm, and radiant intensity of 0.2 mW/sr minimum and 0.8 mW/sr typical. The forward voltage is 1.2 V typical and 1.5 V maximum under the same current and temperature conditions, with reverse current limited to 10 µA maximum at VR=5 V.
Assembly and storage limits are defined for moisture-sensitive handling and soldering control. Before opening the moisture proof bag, storage is specified at 30°C or less and 90% RH or less. After opening, storage is 30°C or less and 60% RH or less with a 168 hour / 7 day floor life. Reflow soldering is limited to no more than two times, and soldering iron work is specified below 350°C for 3 seconds maximum once per terminal.
