So it is as well to research transistors and get those with close to or better than the originals.

The frequency is unknown to me, but I know it’ll be very high. Please, I really want to understand these things better, any help would be appreciated. Is it energy that’s converted to heat? So, where can I search for transistor equivalents now?

The datasheet for D can be found here: The 2SD seems to have an even lower Vcesat curve. Jun 21, 6. Apr 5, 18, 3, So, as Bertus says, post any data you have. Quote of the day. In the saturated region the transistor acts as a switch with Vcesat across it, regardless of the supply. Hardware, Tools, and Toolchain This is Part 1 of a step-by-step guide to bringing custom microcontroller designs to life.


No, create an account now. Jun 21, 4. However I think there is another explanation. Datasheet archive had this feature, but for some reason they took it away!

So, in future, which Transistors can I use in the place of “2SC”? Jun 21, 5.

Then there are usually many possible substitution options. This is the voltage across the transistor when it is on.

The current Transistr is determined by the external circuit so power equals Vce x Ic You are operating in the saturated region.

Yes, my password is: That’s a better datasheet than I found, thanks Steve.

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. These transistors are operated in saturated mode, not analog mode so the Collector power dissapation is not a relevant factor.

What is the Pd? Hello Carel, welcome to AAC. Jun 21, 3. Jul 3, 2, These tables work best when good engineering practice has been adhered to in the design and the components are comfortably within their operating areas. May 16, 1 0. Hello, Can you post a schematic? 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.


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. 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.

Someone else also told me I can use 2SD series, but where do I find it? Jun 21, 9.

Because for 2SC I can’t get 80W. Unfortunately published ‘equivalents’ are rarely that. 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. Many far eastern transistors are labelled without the 2S. One transistpr is to cool the transistor down, this will work, but is it really the solution?
