The transient peak current is the maximum non-recurring peak current the devices can withstand without damaging the LED die and wire bonds. It is not recommended that the device be operated at peak currents beyond the Absolute Maximum Peak Forward Current. 1-84 Electrical/Optical Characteristics at T, = 25C T-13/4 Low Test Symbol Description T-134 | Dome | T-1 | Min. | Typ. | Max. | Units Conditions ApraK Peak Wavelength 3750 3390 | 1340 635 nm Measurement 3850 3490 | 1440 583 at Peak 3950 3590 | 1540 565 D640 K640 558 ha Dominant Wavelength 3750 3390 | 1340 626 nm Note 1 3850 3490 | 1440 585 3950 3590 | 1540 569 D640 K640 560 AAl/e Spectral Line Halfwidth 3750 3390 | 1340 40 nm 3850 3490 | 1440 36 3950 3590 | 1540 28 D640 K640 24 Ts Speed of Response 3750 3390 | 1340 90 ns 3850 3490 | 1440 90 3950 8590 | 1540 500 D640 K640 3100 Cc Capacitance 3750 3390 | 1340 11 pF Vp = 0, f = 1 MHz 3850 3490 | 1440 15 3950 3590 | 1540 18 D640 K640 35 R@j.p~ | Thermal Resistance 3750 3390 210 | CAV | Junction to 3850 3490 210 Cathode Lead 3950 3590 210 D640 510 1340 290 1440 290 1540 290 K640 290 Ve Forward Voltage 3750 3390 | 1340] 1.5 1.9 2.6 Vv Ip = 20 mA 3850 | 3490 | 1440] 1.5 | 2.1 2.6 (Figure 3) 3950 3590 | 1540] 1.5 2.2 3.0 D640 K640 2.2 3.0 Va Reverse Breakdown 3750 3390 | 1340] 5.0 v Ir = 100 pA Voltage 3850 3490 | 1440 3950 3590 | 1540 D640 K640 Ty Luminous Efficacy 3750 3390 | 1340 145 lumens | Note 2 3850 3490 | 1440 500 watt 3950 3590 | 1540 595 D640 K640 655 Notes: 1. The dominant wavelength, A,, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device. 2. The radiant intensity, I,, in watts per steradian, may be found from the equation I, = Iy/ny, where I, is the luminous intensity in candelas and ny is the luminous efficacy in lumens/watt. 1-85 Red, Yellow, and Green 1.0 EMERALD GREEN GREEN \~ HIGH EFFICIENCY RED Ta=25C YELLOW / RELATIVE INTENSITY & a 500 550 600 650 WAVELENGTH - nm Figure 1.
