Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine.
When I replace it with a BC, the circuit doesn’t work at all. Adding schematic to show what I mean: Can you clarify position of additional 10R resistor? Hi, Attila, thanks 2sc2001 much for prompt reply. Sign up or datasheer in Sign up using Google. This is from 2SC datasheet: Sign up using Facebook.
Vce would be much higher than 1. But it will be lower, say it is mA. Home Questions Tags Users Unanswered. I Googled about, and tried to replace it with a BC How do you know that your transistor is the only problem in your circuit?
I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means.

This would severely limit the lifetime of an already stressed component. It depends on your batch.
Chupacabras 3, 2 11 So, transistor could overheat by high Vce or Ic. This is from BC datasheet: The additional resistor dampens this oscillation. But you can see that in some situations there are differences between BC and 2SC Post as a guest Name.
Is it possible that there is another problem which caused your transistor to fail and which makes your new transistor hot?
So power dissipation would be mW, which is above maximum allowed power dissipation. The BC got kind of warm, and didn’t work. This is your circuit: BC hFE from to BC doesn’t seem suitable Ask Question. Another relevant difference could be in hFE. 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 2sc20011 resistor that goes to the feedback path and see whether that improves the situation.
So, is there something ‘special’ about the C trannies? I have short-term access to another C – putting that in the circuit works just fine, so I know the transistor is the issue. Thanks, any help appreciated! My previous, sort-of related question is here: The switching transistor shouldn’t go into breakdown.
Email Required, but never shown. Thanks for that, but just want to clarify where do I put the resistor?
