L173ED

The L173ED is designed as one kind of 2.5x5mm rectangular solid lamps of orange. The orange source color device is made with Gallium Arsenide phosphide on Gallium. Its dice would be orange (GaAsP/GaP).

L173ED has four features. (1)Low power consumption. (2)I.C. compatible. (3)Rounded end rectangular shape. (4)Long life-solid state reliability. Those are all the main features.

Some absolute maximum ratingsof L173ED have been concluded into several points as follow. (1)Its power dissipation would be 105mW. (2)Its DC forward current would be 25mA. (3)Its peak forward current (1/10 duty cycle, 0.1ms pulse width) would be 160mA. (4)Its reverse voltage would be 5V. (5)Its operating temperature range would be from -40°C to 85°C. (6)Its storage temperature range would be from -40°C to 85°C. (7)Its lead solder temperature 4mm below package base would be 260°C for 5 seconds. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of L173ED are concluded as follow. (1)Its peak wavelength would be typ 627nm at IF=20mA. (2)Its dominate wavelength would be typ 625nm with test conditions of IF=20mA. (3)Its spectral line halfwidth would be typ 45nm with test conditions of IF=20mA. (4)Its capacitance would be typ 15pF with test conditions of VF=0V and f=1MHz. (5)Its forward voltage would be typ 2.0V and max 2.5V with test conditions of IF=20mA. (6)Its reverse current would be max 10uA with test conditions of Vr=5V. (7)Its lens type would be orange diffused. (8)Its lv at 10mA would be min 3mcd and typ 8mcd. (9)Its viewing angle would be 100°. And so on. At present we have not got so much information about this IC and we would try hard to get more.
