Not AV related, but hopefully someone on here can help with a basic transistor question. I have just built a circuit which requires up to 0.8W to be dissipated across a normal NPN transistor. Problem is that the Ptotal limit on the transistor I have chosen is 0.8W To get around this I wired two transistors in parallel (base to base, collector to collector, emitter to emitter). The theory being that they would automatically carry half the power each. Problem is that one transistor still seems to be carrying all the power (one gets really hot and the other stays cold to the touch). I have since read that transistors in parallel can be prone to this if not properly balanced. The solution appears to be to add a low resistance (0.1 Ohms) between each emitter and ground. This forces the transistors to "current share". I have pieced this much together from various pages on the web, but not found an article specifically on it. Please could someone who knows what they are talking about confirm or deny? Cheers, and sorry for the off-topic post!
