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. When I replace it with a BC, the circuit doesn’t work at all. Hi, Attila, thanks so much for prompt reply.

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

But you can see that in some situations there are differences between BC and 2SC So power dissipation would be mW, which is above maximum allowed power dissipation. This would severely limit the lifetime of an already stressed component. Chupacabras 3, 2 11 Can you clarify position of additional 10R resistor? The additional resistor dampens this oscillation.

My previous, sort-of related question is here: Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine. This is your circuit: Another relevant difference could be in hFE. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Home Questions Tags Users Unanswered. BC hFE from to BC doesn’t seem suitable Ask Question. Email Required, but never shown. Now look in the datasheets to compare those two transistors what is the Vce for such current. It is off the chart, it is a bad sign for this situation. Thanks for that, but just want to clarify where do I put the resistor?

This is being used in a flyback circuit, which switches at approx ummm kHz or so. This is from 2SC datasheet: So, is there something ‘special’ about the C trannies? The BC got kind of warm, and didn’t work. What type of voltage booster circuit is this? If not, you have to take out a good oscilloscope and look at the waveforms. Base current is not a problem, it is limited by R to 4. Attila Kinali 1, 1 9. But it will be lower, say it is mA. This is from BC datasheet: Sign up using Email and Password.

I Googled about, and tried to replace it with a BC What could cause transistor to overheat? I do not say your circuit is drawing mA, peaks could be higher or lower.

I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means. 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. Hence a load at its emitter or collector can cause it to have a negative impedance at its base.

I have a circuit in which the C aka 2SC transistor failed after many years. By clicking “Post Your Answer”, you acknowledge dtasheet you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of datahseet website is subject to these policies.

Well, it’s whether excessive base current, or excessive product of Ic x Vce. 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. Sign up using Facebook.

Adding schematic to show what I mean: The switching transistor shouldn’t go into breakdown. There are huge differences: So, transistor could overheat by high Vce or Ic. Thanks, any help appreciated! Vce would be much higher than 1. How do you know that your transistor is the only problem in your circuit?

It depends on your batch.
