sorry all... i feel like a dill :'( I have just measured my diode again - directly at the diode 2.8volts 180mA. If I measure at the output of my DDL circuit I get 3.6volts this when I have one multimeter in series measuring current.

These are the stats I have for a SLD1236VL:- Item Symbol Typ. Unit Threshold current Ith 50 mA Operating current Iop 130 Operating voltage Vop 2.5 V Wavelength [ch955]p 658 nm Radiation angle Parallel [ch952]// 9.0 deg...

Jayrob = have you measured this? If this is the case then I have something wrong or my diode is not the same. I would have thought that you should give the diode the correct voltage = i.e if it is rated at 2.8volts then thats all you should give it. If I wanted to give my diode 150ma + I...

wouldnt 295ma give the diode a considerably high voltage - i.e around 5 or 6 volts.. if 100ma is 3 volts then I would expect 295ma to be really high...

Hi All, I have built a current limiter circuit - DDL's. What I am trying to work out is what mA and Voltage is ideal for my laser diode that I have salvaged out of a 16X DVD-RW drive. I think the diode is a closed - looks like the senkat ones. It is not from a Pioneer drive which has a open...
