一、 尺寸；Size
二、描述；Description
L5IR4P-B系列發射管是采用GaAlAs技術的高功率紅外發射二極管，采用藍色的塑料封裝。在一個相似的波長內與標準GaAs比較，GaAlAs技術的這些發射二極管達到超過100%輻射功率改善。正向電壓在低電流和高脈沖電流工作條件下大致對應于標準技術。
所以這些發射二極管是理想的作為標準發射器件的高性能產品。
L5IR4P-Bis a high efficiency infrared emitting diode in GaAlAs technology, molded in BLUE, 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.
