TEC matching

[polishedball]

Looking at getting away from running TEC controllers, anyone have an idea of power dissipation needed for some of the average diodes so I don't have to experiment. Example what watt tec would be needed to hold a p73 diode driven around a watt at 80 degrees. Thoughts or a formula.

Ideally i I just want to run the tec wired to power and then have it hold near room temp. I know this will vary with how much it is modulated but approx ballpark to be in.

Thanks

Here is a general link and a specific possibility.

I'd pick something that would pull about 4W from the diode and can maintain 10-30C below ambient at the available voltage. Then, insert resistors to drop the potential across the TEC and target your 80F goal.
