2N2222UA Transistor Derating Curves
The derating Graph is for a 2N2222A [2N2221A] in a surface mount package. Use the links below for additional derating information covering different package styles. The most common surface mount package would be a SOT23 device but is not qualified by this military specification.
The 2N2222 in this package style will operate up to 50C with the need for derating.
PWB layout hint; increase the pad size to dissipate more heat into the board and away from the 2N2222 package.
