It depends on your batch. Vce would be much higher than 1. What could cause transistor to overheat?

I do not say your circuit is drawing mA, peaks could be higher or lower. Is it possible that there is another problem which caused your transistor to fail and which makes your new transistor hot? Hi, Attila, thanks so much for prompt reply.
This is from 2SC datasheet: So power dissipation would be mW, which is above maximum allowed power dissipation. When I replace it with a BC, the circuit doesn’t work at all. I have a circuit in which the C aka 2SC transistor failed after many years. I have short-term access to another C – 2sc200 that in the circuit works just fine, so I know the transistor is the issue. So, transistor could overheat by high Vce or Ic. Sign up or log in Sign up using Google.
This is being used in a flyback circuit, which switches at approx satasheet kHz or so. 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.

There are huge differences: 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 dataseet 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: This would severely limit the lifetime of an already stressed component. So, is there something ‘special’ about the C trannies?
The switching transistor shouldn’t go into breakdown. But it will be lower, say it is mA.

Suitable replacement datwsheet 2SC transistor? Thanks, any help appreciated! The additional resistor dampens this oscillation. The BC got kind of warm, and didn’t work.
Another relevant difference could be in hFE.
