Thanks so much for your time. The datasheet of the transistors will tell you most of this, like maximum temperature allowed and the heat flow resistance of the transistor. The gain 2cs3281 the pass transistors is low which is why Darlingtons are recommended as an improvement and the supply differential amp gain is also low Which is why he recommended an op amp.

May 6, 7. Be very weary with NTE parts, they are known to be remarked devices that does not match the original parts spec what so ever. Yeah, I’ll be attaching it to the aluminum chassis for heatsinking Save on Transistors Trending price is based on prices over last 90 days. May 5, 4. New and Original Toshiba.

Feb 11, 5, 1, Hopefully I’ll be ok. Wonder if I understood the first part 2sc3821 that design correctly as 2sc33281 as Vin goes.

It’s a character flaw, or the fact that I’m where the town where the phrase “New York Second” originated It goes into current limit mode at about 1. May 5, 6. Hello, Have a good look at the transformers connections. May 6, 8. Your name or 2ec3281 address: I made some remarks in the schematic you posted: The “off” amount and percentage simply signifies the calculated difference between the seller-provided price for the item 2s3c281 and the seller’s price on eBay.


I can’t imagine that a book like this would be put out if it gave unsafe information. The unit will provide two independently adjustable outputs, positive and negative of about 4V to 15V each, as well as a ground.

I think I got the wrong form factor for the mica, but I bet I can make it work Yes, my password is: May 5, 5. That can be used to calculate the worst 2sc33281 heat dissipation in the power transistors.

You may also like. Note this thread, as someone else here was also using this book. Jun 11, 46 0. Do you already have an account? May 7, 2cs3281. The metal chassis is not “heatsinking” when you are using W 15A power transistors!

Skip to main content. You May Also Like: You’re going to be using one or two chunks of aluminum about the size of your fist. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic 2s3281. Microcontroller and possible compatible replacements. May 5, 3. The emphasis on safety in the book is quite big, so I imagine that “heatsinking” Q1 and Q2 to the chassis shouldn’t be unsafe.


Resistance to heat flow is called, “theta” and this resistance is always defined as between two places.

Another improvement he talks about involves this schematic, showing only the positive regulator The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. This design seems good for learning though. Repaired my German 12vdc 20amp power supply for Ham Radio. I also picked up some mica and thermal compound. Well, the deed is done. I’m new to this. The power you need to get rid of is 45 watts at the worst.

May 4, 1.

To compensate for this the raw input supply is high so that Q3 and Q4 can draw enough current through R1 and R2 to supply the pass transistor base drive and and also their own needs. Feb 16, Again, please forgive my ignorance. You might have some good luck with the MJE series parts.
