This is your circuit: Can you clarify position of additional 10R resistor?

Another relevant difference could be in hFE. Adding schematic to show what I mean: 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.

Email Required, but never shown. The switching transistor shouldn’t go into breakdown. It depends on your batch. How do you know that your transistor is the only problem in your circuit?

My previous, sort-of related question is here: So power dissipation would be mW, which is above maximum allowed power dissipation. It is off the chart, it is a bad sign for this situation. The additional resistor datasneet this oscillation. Sign up using Email and Password. Thanks, any help appreciated!

Sign up using Facebook. 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. Suitable replacement for 2SC x2001 BC doesn’t seem suitable Ask Question.

Base current is not a problem, it is limited by R to 4. Hi, Attila, thanks so much for prompt reply. This is from BC datasheet: Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine. What type of voltage booster circuit is this?

This is from 2SC datasheet: Now look in the datasheets datashfet compare those two transistors what is the Vce for such current. So, is there something ‘special’ about the C trannies?

BC hFE from to I do not say your circuit is drawing mA, peaks could be higher or lower. Attila Kinali 1, 1 9. Post as a guest Name. I have short-term access to another C – putting that in the circuit works just fine, so I know the transistor is the issue.


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

I have a circuit in which the C aka 2SC transistor failed after many years. There are huge differences: Home Questions Tags Users Unanswered.

This would severely limit the lifetime of an already stressed component. But it will be lower, say it is mA.

Hence a c001 at its emitter or collector can cause it to have a negative impedance at its base. Well, it’s whether excessive base current, or excessive product of Ic x Vce. Chupacabras 3, 2 11 I have seen them referred to as ‘switching’ transistors datashset, I don’t know what that specially means.
