Jun 21, 1. Jun 21, 7 0. Datasheet archive had this feature, but for some reason they took it away!

So, where can I search for transistor equivalents now? Please, I really want to understand these things better, any help would be appreciated. Jun 21, 2. Apr 5, 18, 3, Hello, Can you post a schematic?


Attached is a smal XLS file with transistor daatsheet, in a zipfile. Jun 21, 3. Nov 9, 5, Hello Carel, welcome to AAC. I see that you already posted in another electronics forum and they think the the different responses of transistors was due to your mounting methods. However I think there is another explanation. You are correct in observing that the supply of free data sheets on the web has diminished in favour of sites offering this data for sale. So I have been unable to get full information on all the transistors, in particular on the 2SD Many far eastern transistors dafasheet labelled without the 2S.

But the datssheet I have found suggests that the 2SC has a particularly low Vce sat – a parameter that you did not mention.

This is the voltage across darasheet transistor when it is on. These transistors are operated in saturated mode, not analog mode datashfet the Collector power dissapation is not a relevant factor. Your computer power supply will be in the range – watts so the transistors will be passing 1 – 2 amps at rectified mains voltages.


The other parameters you ask about are relevant as the transistor can dissapate very high powers for short periods turning off whilst both the full supply voltage is present and the current is still flowing. So, as Bertus says, post any data you have. Jun 21, 4.

Jul 3, 2, The Vce saturation voltage difference is definitely a good explanation, but it might not be the full explanation. The switching speed can also be important depending on the circuit.

If the power supply uses a high switching frequency, then a faster transistor will run cooler since it spends much less time in the linear region during transitions. Studiot datxsheet this briefly above, and it may be the dominant effect since modern switching supplies use high frequency and the old style power transistors were not designed for this use. Jun 21, 5. One solution is to cool the transistor down, this will work, but is it really the solution?

The datasheet for D can be found here: You can also visit http: Jun 21, 6. Jun 21, 7. The 2SD seems to have an even lower Vcesat curve. Thank you for the link.

Datsaheet 21, 8. Someone else also told me I can use 2SD series, but where do I find it? And how do I know the D is a 2SD seires, since this specific transistor came from China, which might be something with a similar name Then it uses 2x “2SC” originals were “D”.

And lastly it uses 4x 2SC The frequency is unknown to me, but I know it’ll be very high.

So, in future, which Transistors can I use in the place of “2SC”? Jun 21, 9.


Jun 21, Remember, all datasheets, for anything, can be found at www. Because for 2SC I can’t get 80W. What is the Pd? Is it energy that’s converted to heat? That’s a better datasheet than I found, thanks Steve. Unfortunately published ‘equivalents’ are rarely that.

These tables work best when good engineering practice has been adhered to in the design and the components are comfortably within their operating areas.

Then there are usually many possible substitution options. When components, particularly critical highly stressed ones, are operated near their datsheet substitution becomes more difficult.

Sometimes it is not even possible to substitute the same type number from a different manufacturer as there are always subtle differences between different suppliers products. So it is as well to research transistors and get those with close to or better than the originals. You are looking for shorter turn on, turn off and storage times and lower Vcesat at the currents operating. Transistors have two regions of operation.

In the saturated region the transistor acts as a switch with Vcesat across it, regardless of the supply.

The current Ic is determined by the external circuit so power dxtasheet Vce x Datashdet You are operating in the saturated region. Apr 15, May 16, 1 0.
