Base current is not a problem, it is limited by R to 4. Sign up or log in Sign up using Google. I have a circuit in which the C aka 2SC transistor failed after many years.

Suitable replacement for 2SC transistor? Thanks, any help appreciated! This is being used in a flyback circuit, which switches at approx ummm kHz or so.

I Googled about, and tried to replace it with a BC Attila Kinali 1, 1 9. How do you know that your transistor is the only problem in your circuit? So, is there something ‘special’ about the C trannies? But it will be lower, say it is mA. Another relevant difference could be in hFE.

Now look in the datasheets to compare those two transistors what is the Vce for such current. My previous, sort-of related question is here: 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. What type of voltage booster circuit is this? What could cause transistor to overheat?


Hence a load at its emitter or collector can cause it to have a negative impedance at its datashert. The BC got kind of warm, and didn’t work. If not, you have to take out a good oscilloscope and look at the waveforms.

But you can see that in some situations there are differences between BC and 2SC Email Required, but never shown.

I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means. Sign up using Facebook. This is from BC datasheet: When I replace it with a BC, the circuit doesn’t work at all.

Chupacabras 3, 2 11 The additional resistor dampens this oscillation. Datashheet you clarify position of additional 10R resistor? Is it possible that there is another problem which caused your transistor to fail and which makes your new transistor hot? Thanks for that, but just want to clarify where do I put the resistor?

So, transistor could overheat by high Vce or Ic. 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 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. Well, it’s whether excessive base current, or excessive product of Ic x Vce. BC hFE from to Vce would be much higher than 1. 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.

So power dissipation would be mW, which is above maximum allowed power dissipation. There are huge differences: BC doesn’t seem suitable Ask Question.

This is your circuit: This would severely limit the lifetime of an already stressed component. Hi, Attila, thanks so much for prompt reply.

It depends on your batch. Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine. Post as a guest Name. This is from 2SC datasheet: Home Questions Tags Users Unanswered. It is 2s2001 the chart, it is a bad sign for this situation.
