Works well, but incorrect data.

Comments about RadioShack TIP3055 NPN Transistor:

I bought two of these(one as a backup) to use in a fluorescent lamp inverter. Since you will likely need this in a high power application, a heat sink may needed.

A few things to note on this product:
First, incorrectly labeled, it's really a MJE3055T however I already was aware of it.

Second, do NOT believe the ratings on this page as nearly all of them are incorrect.
It's correct max ratings are: I(C) of 10A, and Power Dissipation of 75Watts.

Google "MJE3055T" to find the correct data sheet.

            Comments about RadioShack TIP3055 NPN Transistor:

            The transistor works fine, but its NOT a TIP3055... its a MJE3055, which is rated at 75W not 90W.
