My previous, sort-of related question is here: Hence a load at its emitter or collector can cause it to have a negative impedance at its base. I do not say your circuit is drawing mA, peaks could be higher or lower. It depends on your batch. There are huge differences: Can you clarify position of additional 10R resistor?

Transistor Catalog Post as a guest Name. Suitable replacement for 2SC transistor? The additional resistor dampens this oscillation. Vce would be much higher than 1. What could cause transistor to overheat? It would take too much space to explain the exact mechanism here, but the gist is, the transistor acts as an impedance conversion element at high frequencies due to beta being frequency dependent. Thanks, any help appreciated! Sign up or log in Sign up using Google.

If not, you have to take out a good oscilloscope and look at the waveforms. Attila Kinali 1, 1 9. Seeing that your circuit has no feedback resistor anywhere on the 2SC, I would suggest to try adding a 10R resistor in the base of the 2SC resp BC after the 22R resistor that goes to the feedback path and see whether that improves the situation. Is it possible that there is another problem which caused your transistor to fail and which makes datashdet new transistor hot? Sign up using Facebook.

But it will be lower, say it is mA. C Datasheet catalog Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine. Home Questions Tags Users Unanswered. It is off the chart, it is a bad sign for this situation. This is being used in a flyback circuit, which switches at approx ummm kHz or so. What type of voltage booster circuit is this? I have a circuit in which the C aka 2SC transistor failed after many years. But you can see that in some situations there are differences between BC and 2SC Base current is not a problem, it is limited by R to 4.

Hi, Attila, thanks so much for prompt reply. This would severely limit the lifetime of an already stressed component. Another relevant difference could be in hFE.
