Note: Driving these high power devices at currents less than the test conditions may produce unpredictable results and may be subject to variation in performance. Pulse width modulation is recommended for dimming effects. 0 50 100 150 200 250 300 350 400 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 V F - Forw ard V oltage (V olts) 0 3 6 9 12 15 18 21 800 600 700 500 400 200 100 300 0 0.2 0.4 0.6 0.8 1 1.2 0 100 200 300 400 I F - A verage Forw ard Current (mA ) 200 400 600 800 0.0 0.2 0.4 0.6 0.8 1.0 1.2 0 100 200 300 400 I F - A v erage Forw ard Current (mA ) 0 200 400 600 800 Note: Driving these high power devices at currents less than the test conditions may produce unpredictable results and may be subject to variation in performance.
