Hi all,
I've registered to this forum simply to ask a question regarding my transistor
I have a circuit which is powered by 12v, my transistor is getting really hot (cannot touch it for long before it burns my fingers!). My circuit works fine for a short amount of time, then it just stops functioning. if I turn off the power for a few hours and come back, it's working again.
Does this sound like a heat problem? Would the heat prevent the transistor from functioning? I am new to electronics but the project I'm doing is almost done, it's just annoying that it only works for 5-10 minutes before deciding to give up.
All details are below for the type of transistor I'm using...

Thanks in advance people!
