Recommendation on how to Derate a Transistor

Starting with the long list of Transistor Derating Curves, I added in several transistor links to Transistor Derating Guidelines [which is the new page]. Or, recommendations on how to derate a transistor based on a linear equation, with no graphic [Derating Curve].

The new transistor links pick up missing devices in the list, but because I didn't have a derating chart they all point to the new page which provides the derating recommendation for each of the devices. The recommendation for each transistor is how much to decrease power dissipation over increasing temperature, mW/C [and that's all].

Two of the main links off the transistor derating page are NPN Derating Curves, and PNP Derating Curves, but I don't have any plans to add the new links to either of those pages.

Individual transistor pages not yet listed in the blog;
2N3250 Derating Curve.
2N3467 Derating Curve.
2N3485 Derating Curve.
