Product Overview
The EL_IR204-A is an EVERLIGHT infrared emitting diode in the LED category. The datasheet identifies the LED part number as IR204-A, using GaAlAs chip material with a blue lens. Its mechanical format is a 3.0 mm T-1 blue plastic package with 2.54 mm lead spacing.
At IF=20 mA and Ta=25°C, the diode has a 940 nm typical peak wavelength, 45 nm typical spectral bandwidth, and 4.0 mW/sr minimum to 5.6 mW/sr typical radiant intensity. The forward voltage at the same current is 1.2 V typical and 1.5 V maximum, with 10 uA maximum reverse current at VR=5 V and a 35 degree typical view angle.
For pulsed operation, the datasheet lists 38 mW/sr typical radiant intensity at IF=100 mA and 350 mW/sr typical at IF=1 A, both with pulse width <=100 us and duty <=1%. Absolute maximum ratings include 100 mA continuous forward current, 1.0 A peak forward current, 5 V reverse voltage, -40 to +85°C operating and storage temperature, 150 mW power dissipation, and 260°C maximum soldering temperature for <=5 seconds.
