TO thermal resistance and beyond

Heat dissipation is a key factor in the design of a power system; in a world where the trend is for more power in a smaller space, are TO-style packages still the best solution?  TO packages were originally intended for discrete transistors, in fact TO stands for ‘transistor outline’. The metal flange that protrudes from the top, or the mounting hole in the packaging, makes them easily identifiable.
