DIY TO-92 heatsink

All out of TO-220’s? Thinking maybe you can eke enough performance out of a smaller transistor?

Want to squeeze a bit more current through those inexpensive TO-92 package transistors? Then add a small metal heatsink. I made this for a PWM DC motor driver, as some 2N2222 bi-polar transistors were handy.

Of course, we should only operate components within their factory spec, but it’s good to know this type of desperation has been previously explored – just in case. –Link
