Please, I really want to understand these things better, any help would be appreciated. One solution c502s7 to cool the transistor down, this will work, but is it really the solution? Your name or email address: Many far eastern transistors are labelled without the transjstor. 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 Jun 21, 6.

Apr 15, Remember, all datasheets, for anything, can be found at www. Jun 21, 7 0. In c0527s saturated region the transistor acts as a switch with Vcesat across it, regardless of the supply.

Do you already have an account? Jun 21, 7. So, in future, which Transistors can I use in the place of “2SC”? Nov 9, 5, But the information I have found suggests that the 2SC has a particularly low Vce sat – a parameter that you did not mention.

Jun 21, 4. These transistors are operated in saturated mode, not analog mode so the Collector power dissapation is not a relevant factor. Unfortunately published ‘equivalents’ are rarely that.


That’s a better datasheet than I found, thanks Steve. Jun 21, 8.

These tables work best when good engineering practice has been adhered to in the design and the components are comfortably within their operating areas. No, create an account now. The 2SD seems to have an even transisotr Vcesat curve. Transistog Vce saturation voltage difference is definitely a good explanation, but it might not be the full explanation. 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.

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.

Jun 21, 3. You are looking for shorter turn on, turn off and storage times and lower Vcesat at the currents operating.

Hello Carel, welcome to AAC. Hardware, Tools, and Toolchain This is Part 1 of a step-by-step guide to bringing custom microcontroller designs to life.

May 16, 1 0.

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

The switching speed trnsistor also be important depending on the circuit.

Because for 2SC I can’t get 80W. Jun 21, When components, particularly critical highly stressed ones, are operated near their limits substitution becomes more difficult. Then it uses 2x “2SC” originals were “D”. Apr 5, 18, 3, Your computer power supply will be in the range – watts so the transistors will be passing 1 – 2 amps at rectified mains voltages. Quote of the day.

Datasheet archive had this feature, but for some reason they took it away! 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. Jun 21, 2. Jul 3, 2, The frequency is unknown to me, translstor I know it’ll be very high. Jun 21, 5. You May Also Like: If the power supply uses a high switching frequency, then a faster transistor will run cooler since it spends much traneistor time in the linear region during transitions.

This is the transiztor across the transistor when it is on. However I think there is another explanation. You can also visit http: Studiot mentioned 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, 1. So I have been unable to get full information on all the transistors, in particular on the 2SD Is it energy that’s converted to heat?

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.
