It is off the chart, it is a bad sign for this situation. But you can see that in some situations there are differences between BC and 2SC Now look in the datasheets to compare those two transistors what is the Vce for such current. This would severely limit the lifetime of an already stressed component.

How do you know that your transistor daatasheet the only problem in your circuit? 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.


What type of voltage booster circuit is this?

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. Hence a datqsheet 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. So, transistor could overheat datahseet high Vce or Ic.

This is your circuit: I have seen them referred datasyeet as ‘switching’ transistors somewhere, I don’t know what that specially means. Home Questions Tags Users Unanswered. But it will be lower, say it is mA.

So power dissipation would be mW, which is above maximum allowed power dissipation. It depends on your batch. Suitable replacement for 2SC transistor? Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine.

I Googled about, and tried to replace it with a BC There are huge differences: Vce would be much higher than 1. So, is there something ‘special’ about the C trannies?


BC doesn’t seem suitable Ask Question. This is from BC datasheet: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Thanks, any help appreciated!

The additional resistor dampens this oscillation. When I replace it with a BC, the circuit doesn’t work at all. This is from 2SC datasheet: Adding schematic to show what I mean: What could cause transistor to overheat? The switching transistor shouldn’t go into breakdown. I do not say your circuit is drawing mA, peaks could be higher or lower. Thanks for that, but just want to clarify where do I put the resistor?

Another relevant difference could be in hFE. Chupacabras 3, 2 11 Well, it’s whether excessive base current, or excessive product of Ic x Vce. My previous, sort-of related question is here: Hi, Attila, thanks so much for prompt reply.
