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. Email Required, but never shown. Attila Kinali 1, 1 9.
When I replace it with a BC, the circuit doesn’t work at all. Another relevant difference could be in hFE.

What type of voltage booster circuit is this? Is it possible that there is another problem which caused your transistor to fail and which makes your new transistor hot? Base current is not a problem, it is limited by R to 4.
BC doesn’t seem suitable Ask Question.

So, transistor could overheat by high Vce or Ic. Adding schematic to show what I mean: This would severely limit the lifetime of an already stressed component. I have short-term access to another C – putting that in the circuit works just fine, so I know the transistor is the issue.
I have a circuit in which the C aka 2SC transistor failed after many years. Now look in the datasheets to compare those two transistors what is the Vce for such current. Chupacabras 3, 2 11 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. The BC got kind of warm, and didn’t work.
This is from BC datasheet: This is from 2SC datasheet: The switching transistor shouldn’t go into breakdown. Sign up or log in Sign up using Google. Thanks, any help appreciated! I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what datasehet specially means. Post as a guest Name.

Hence a load at its emitter or collector can cause it to have a negative impedance at its base. BC hFE from to Suitable replacement for 2SC transistor? So, is there something ‘special’ about the C trannies? Sign up using Facebook. I Googled about, and tried to replace it with a BC What could cause transistor to overheat? Well, it’s whether excessive base current, or excessive product of Ic x Vce.
Hi there Chupacabras, when I replace it with a 2xc2001 C the whole circuit works just fine. This is your circuit: This is being used in a flyback circuit, which switches at approx ummm kHz or so.
