So, transistor could overheat by high Vce or Ic.

Thanks, any help appreciated! So power dissipation would be mW, which is above maximum allowed power dissipation.

The additional resistor dampens this oscillation. Base current is not a problem, it is limited by R to 4. When I replace it with a BC, the circuit doesn’t work at all. So, is there something ‘special’ about the C trannies? This is being used in a flyback circuit, which switches at approx ummm kHz or so. Sign up using Email and Password. BC hFE from to Suitable replacement for 2SC transistor? I have a circuit in which the C aka 2SC transistor failed after many years.

How do you know that your transistor is the only problem in your circuit? But you can see that in some situations there are differences between BC and 2SC BC doesn’t seem suitable Ask Question. Sign up or log in Sign up using Google.


I do not say your circuit is drawing mA, peaks could be higher or lower. My previous, sort-of related question is here: This is your circuit: Sign up using Facebook. Thanks for that, but just want to clarify where do I put the resistor?

Another relevant difference could be in hFE. Attila Kinali 1, 1 9. Seeing that your circuit has no feedback resistor anywhere on the 2SC, I would suggest to datashest 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.

Adding schematic to show what I mean: 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 2c001 problem which caused your transistor to fail and which makes your new transistor hot?

I Googled about, and tried to replace it with a BC Chupacabras 3, 2 11 Now look in the datasheets to compare those two transistors what is the Vce for such current. Can you clarify position of additional 10R resistor? It depends on your batch. What type of voltage booster circuit is this? Home Questions Tags Users Unanswered.

I have seen them referred to as datawheet transistors somewhere, I don’t know what that specially means.

Vce would be much higher than 1. This is from BC datasheet: But it will be lower, say it c200 mA. This is from 2SC datasheet:
