Hi team, I went to the local store and grabbed some 1N5404 silicon diodes and a 5 W 1 ohm resistor. Since I'm building a 2 W 445nm laser there is a need to set the current as high as ~1.8 A and my old dummy load would get extremely hot and the diodes would fail to stand so much load. Anyway, I don't know how many of those diodes to use so I can simulate a 445 at 1.8 Amps. Here is the datasheet for those who are not familiar with these high diodes. http://www.datasheetcatalog.org/datasheet/WINGS/1N5406.pdf
I figured that I can determine the vdrop on the diodes on FIG.3 but I'm not sure, since somebody claimed that they would drop 1.1 Volts even at ~2 A. But that's @ 3 A isnt it? I haven't taken any electronics classes yet and I only stuck to the practical side of things without really understand how they work. Please I would appreciate it if you can enlighten me on this.
