Is it possible that there is another problem which caused your transistor to fail and which makes your new transistor hot? 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.

But it will be lower, say it is mA. Chupacabras 3, 2 11 Home Questions Tags Users Unanswered. Post as a guest Name. This is your circuit: Sign up or log in Sign up using Google. BC dztasheet from to This would severely limit the lifetime datashdet an already stressed component.

Hi, Attila, thanks so much for prompt reply. What could cause transistor to overheat? This dtasheet from 2SC datasheet: What type of voltage booster circuit is this? So, transistor could overheat by high Vce or Ic.

Vce would be much higher than 1. Thanks for that, but just want to clarify where do I put the resistor?

But you can see that in some situations there are differences between BC and 2SC So, is there something ‘special’ about the C trannies? I Googled about, and tried to replace it with a BC Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine.

Hence a load at its emitter or collector 2sc200 cause it to have a negative impedance at its base. The additional resistor dampens this oscillation. My previous, sort-of related question is here: Attila Kinali 1, 1 9. Well, it’s whether excessive base current, or excessive product of Ic x Vce.

I do not say your circuit catasheet drawing mA, peaks could be higher or lower.

Adding schematic to show what I mean: The 2dc2001 got kind of warm, and didn’t work. Can you clarify position of additional 10R resistor? So power dissipation would be mW, which is above maximum allowed power dissipation.

It depends on your batch. It is off the chart, it is a bad sign for this situation.

There are huge differences: 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.

It would take too much 2c2001 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.

The switching transistor shouldn’t go into breakdown. Email Required, but never shown. When I replace it with a BC, the circuit doesn’t work at all. Sign up using Facebook. Base current is not a problem, it is dataasheet by R to 4.
