RL-55

RL-55 is a kind of gallium arsenide phosphide lamp.There are some features as follows.First is high axis intensity.The second is optimum packaging design for maximum strength at minimum linear spacing.Besides, it operates from 5 IC logic supply.Then is minimum axial lead.The fifth is high reliability.The last one is low cost version.The typical applications include mounting on PC borads at low current as diagnostic and circuit status indications.

What comes next is about the RL-55 maximum ratings.The operating and storage temperature range is from -55 to +100.The lead solder time, 260 (0.063 from case) is 5 sec.The peak inverse voltage is 3 V.The continous forward current is 40 mA.The peak forward current(1 s pulse, 0.1% duty cycle) is 250 mA.The power dissipation is 80 mW (TA=25).The derate linearity from 25 is -1.1 mW/.

The following is about the RL-55 electrical/optical characteristics (TA=25).The typical wavelength, peak emission is 660 nm.The typical spectral line half width is 40 nm.The typical viewing angle is 50 Deg.The typical forward voltage is 1.6 V and the maximum is 2.0 V at IF=20 mA.The typical reverse current is 0.15 A and the maximum is 10 A at VR=3 V.The minimum luminous intensity is 2.0 mcd and the typical is 2.2 mcd at IF=10 mA.
