It is off the chart, it is a bad sign for this situation. Is it possible that there is another problem which caused your transistor to fail and which makes your new transistor hot? So, is there something ‘special’ about the C trannies? Chupacabras 3, 2 11 Base current is not a problem, it is limited by R to 4.

Another relevant difference could be in hFE. If not, you have to take out a good oscilloscope and look at the waveforms. Home Questions Tags Users Unanswered.

Post as a guest Name. It depends on your batch. Thanks for that, but just want to clarify where do I put the resistor? The switching transistor shouldn’t go into breakdown. Can you clarify position of additional 10R resistor? BC hFE from to Vce would be much higher than 1. I Googled about, and tried to replace it with a BC The BC got kind of warm, and didn’t work. So, transistor could overheat by high Vce or Ic.

This is from BC datasheet: Sign up using Email and Password. There are huge differences: Hence a load at its emitter or collector can cause it to have a negative impedance at its base. Suitable replacement for 2SC transistor?

I do not say your circuit is c0201 mA, peaks could be higher or lower.

So power dissipation would be mW, which is above maximum allowed power dissipation. When I replace it with a BC, the circuit doesn’t work at all. Sign up using Facebook.

What type of voltage booster circuit is this? 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.

Hi, Attila, thanks so much for prompt reply. I have a circuit in which the C aka 2SC transistor failed after many years. Attila Kinali 1, 1 9. Thanks, any help appreciated!

But you can see that in some situations there are differences between BC and 2SC Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine. Email Required, but never shown. 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.

I have short-term access to another C – putting that in the circuit works just fine, so I know the transistor is the issue. BC doesn’t seem suitable Ask Question.

Adding schematic to show what I mean: How do you know that your transistor is the only problem in your circuit? This would severely limit the lifetime of an already stressed component. Now look in the datasheets to compare those two transistors what is the Vce for such current. I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means.
