WebMay 10, 2014 · One think you got right is that it will be easier to cool the system with multiple transistors, because their Rth j-c ( 1 C/W each) are in parallel. For TIP35 (with 70 W and 140C temperature difference) you would need a total Rth of 2C/W, hence a heatsink of 1C/W. With 3 in parallel you would need a heatsink of 1.6C/W.
