controlling power dissipation a transistor circuit

[ant17]

hi guys i have pretty straightforward question to ask say i had a single npn transistor and i want limit the power dissipation to 150watts so therefore i need to limit collector current but question is what is the best way to accomplish this and what is routine practice in the electronics design industry the only things i come up with a resistive and reactive

what sort of circuit are you using this bjt in ? More details of your circuit might help in getting a better solution.

In the absence of such info, all that can be said is tha power = V x I. In addition, for switching circuits, if you limit the time then you get an advantage.

Hi ant17
A simple hiccup current limiter would suit your aim as well . if you need more information or straight guidance your schematic is required .
