紅外發(fā)射二極管
一、 尺寸；Size
二、描述；Description
L5IR5-60系列發(fā)射管是采用GaAlAs技術(shù)的高功率紅外發(fā)射二極管，采用透明的塑料封裝。在一個相似的波長內(nèi)與標(biāo)準(zhǔn)GaAs比較，采用GaAlAs技術(shù)的這些發(fā)射二極管輻射功率達到超過100%的改善。正向電壓在低電流和高脈沖電流工作條件下大致對應(yīng)于標(biāo)準(zhǔn)技術(shù)。
所以這些發(fā)射二極管是理想的作為標(biāo)準(zhǔn)發(fā)射器件的高性能產(chǎn)品。
L5IR5-60 is a high efficiency infrared emitting diode in GaAlAs technology, molded in clear, blue grey tinted plastic packages
In comparison with the standard GaAs on GaAlAs technology these emitters achieve more than 100 % radiant power improvement at a similar wavelength. The forward voltages at low current and at high pulse current roughly correspond to the low values of the standard technology.
Therefore these emitters are ideally suitable as high performance replacements of standard emitters.
