BC hFE from to Chupacabras 3, 2 11 Well, it’s whether excessive base current, or excessive product of Ic x Vce. Vce would be much higher than 1.

But you can see that in some situations there are differences between BC and 2SC Adding schematic to show what I mean: It is off the chart, it is a bad sign for this situation. When I replace it with a BC, the circuit doesn’t work at all. Post as a guest Name. Thanks for that, but just want to clarify where do I put the resistor?

So, is there something ‘special’ about the C trannies? How do you know that your transistor is the only problem in your circuit? Hence a load at its emitter or collector can cause it to have a negative impedance at its base. Is it possible that there is another problem which caused your transistor to fail and which makes your new transistor hot? The switching transistor shouldn’t go into breakdown.


Suitable replacement for 2SC transistor? Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

This is your circuit: I Googled about, and tried to replace it with a BC 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.

Hi there Chupacabras, when I replace it with a good C datassheet whole circuit works just fine. 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. This would severely limit the lifetime of an already stressed component.

There are huge differences: What could cause transistor to overheat? Home Questions Tags Users Unanswered. The BC got kind of warm, and didn’t work.

What type of voltage booster circuit is this? Email Required, but never shown.

So power dissipation would be mW, which is above maximum allowed power dissipation. But it will be lower, say it is mA. Another relevant difference could be in hFE. I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means. It would take too much space to explain the exact mechanism here, but the adtasheet is, the transistor acts as an impedance conversion element at high frequencies due to beta being frequency dependent.

My previous, sort-of related question is here: Sign up using Email and Password. Thanks, any help appreciated! Can you clarify position of additional 10R resistor?
