Default Re: Mitsubishi LPC-826

If it helps, here is a pinout and power graph of an LPC-826 diode from the OdicForce Lasers site.

Yup, they can take over 500mA and I know from experience.
Yeah, I'm still here and never left just way busy with other life stuff

Default Re: Mitsubishi LPC-826

Meh, no need to push them that hard.

By the time you are at 450 mA (far beyond rated maximum) you'll get little extra for pushing further. Between 450 and 600 mA you get perhaps 10% more output power, which is hardly noticable, but your diode life will suffer greatly for it.

To be honest i'd stick to 300 mA for a good long diode life and go for a more powerful diode if you need it. Often a laser reliably producing 200 mW is better to have than one producing 300 mA with a large chance of suddenly going poof-LED on you.

Default Re: Mitsubishi LPC-826

I've got those wings, and was thinking they're the reason for not getting any burning (at 200mA)....
Is the 450mA mentioned above continuous or peak? Any idea where I can find a graph of recommended duty cycle vs current? Thanks,

Wings are normal on the LPC-826.

Here's a graph of power vs current. It'll vary some between diodes.



Duty cycle is going to depend on how much cooling you have. 450mA is continuous, i.e. not pulsed. I personally wouldn't go above 400mA.
