So power dissipation would be mW, which is above maximum allowed power dissipation. It depends on your batch. Sign up using Email and Password. I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means.

This is from BC datasheet: I have short-term access to another C – putting that in the circuit works just fine, so I know the transistor is the issue. The switching transistor shouldn’t go into breakdown. Hi, Attila, thanks so much for prompt reply.

Chupacabras c20001, 2 11 I Googled about, and tried to replace it with a BC Post as a guest Name. Base current is not a problem, it is limited by R to 4. Adding schematic to show what I mean: Suitable replacement for 2SC transistor?


This is being used in a flyback circuit, which switches at approx ummm kHz or so. How do you know that your transistor is the only problem in your circuit?

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 datassheet frequency dependent. Vce would be much higher than 1.

Hence a load at its emitter or collector datashet cause it to have a negative impedance at its base. But you can see that in some situations there are differences between BC and 2SC Now look in the datasheets to compare those two transistors what x2001 the Vce for such current.

Is it possible that there is another problem which caused your transistor to fail and which makes your new transistor hot? This is your circuit: Attila Kinali 1, 1 9. But it will be lower, say it is mA.

What type of voltage booster circuit is this? The additional resistor dampens this oscillation.

So, transistor could overheat by high Vce or Ic. Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine.


Can you clarify position of additional 10R resistor? Thanks, any help appreciated! BC doesn’t seem suitable Ask Question. I have a circuit in which the C aka 2SC transistor failed after many years. So, is there something ‘special’ about the C trannies?

I do not say your circuit is drawing mA, peaks could be higher or lower. BC hFE from to If not, you have to take out a good oscilloscope and look at the waveforms. Fatasheet previous, sort-of related question is here: This would severely limit the lifetime of an already stressed component.

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.

There are huge differences:
