Please help
I want to place it in parallel is because I have two original chevrolet module transistors and it is not that my car is damaging them only that I want to make a stronger module, the life time of the modules that I have used usually last two years. Today, remove the transistors from the module and place them directly on a computer heatsink with its respective thermal paste. I have been finding out and from what I saw the 2n3904 transistor can be used to control the BU941ZT but I am still not sure and I also read that each transistor must have a low ohm resistor in the E.
I reiterate, why does the original transistor burn? If it is for the issue of power it will work for you, if it is not the same if it has one or forty in parallel. In electronics, the performance of something is improved when something is harmonically oversized with criteria. That transistor already has another inside it, it is a Darlington. If you place two in parallel, a low-value equalizer resistor that sets the working limit point on the transmitter must be placed in such a way that when the specified maximum current circulates, it produces a voltage drop of the conduction voltage BE
Well first of all the modules are not original. Because the originals are much more expensive and as I have several generic brand I want to make a better design so to speak. as I already told you that its life time is two years and I think that as the modules get so hot I thought that with two transistors it would heat up less and so they would last longer. that you recommend me to improve its duration.
Increase the cooling system ... volume, surface, attach for example if the heatsink is Aluminum, Copper that is a better conductor, etc. If the temperature is internal, it is produced by the low surface capacity where the heating elements settle in exchanging the heat generated with the medium. I would tell you that there is where you should work because if they last 2 years according to your sayings, the transistors are well calculated because otherwise they will burn soon after walking.
The module of my car originally came inside the engine distributor and well the surface to dissipate the heat is not very large, incidentally heats up with the wind of the engine, then I grabbed a computer processor heatsink with everything and fan, take out the module of the engine compartment and as the car dashboard has a lot of space for the fan to work and dissipate the heat very well, place the module hidden there and it is very good. I did that about 4 months ago, let's see how it works. Well thank you very much for every friend.
