2SC Datasheet(PDF) – TRANSYS Electronics Limited

The BC got kind of warm, and didn’t work. Well, it’s whether excessive base current, or excessive product of Ic x Vce. If not, you have to take out a good oscilloscope and look at the waveforms. Now look in the datasheets to compare those two transistors what is the Vce for such current. So, is there something ‘special’ about the C trannies?

BC hFE from to My previous, sort-of related question is here: This would severely limit the lifetime of an already stressed component. Hi, Attila, thanks so much for prompt reply. It depends on your batch. Adding schematic to show what I mean: The additional resistor dampens this oscillation.

So, transistor could overheat by high Vce or Ic. Post as a guest Name. Suitable replacement for 2SC transistor? Hi there Chupacabras, when I 2sc22001 it with a good C the whole circuit works just fine.

There are huge differences: Chupacabras 3, 2 11 BC doesn’t seem 2c2001 Ask Question. I have a circuit in which the C aka 2SC transistor failed after many years.

It is off the chart, it is a bad sign for this situation. How do you know that your transistor is the only problem in your circuit?

2SC Datasheet PDF –

Attila Kinali 1, 1 9. Hence a load at its emitter or collector can cause it to have a negative impedance at its base.

Sign up using Email and Password. The switching transistor shouldn’t go into breakdown. Another relevant difference could be in hFE. This is being used in a flyback circuit, which switches at approx ummm kHz or so. 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. Home Questions Tags Users Unanswered.

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. I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means. So power dissipation would be mW, which is above maximum allowed power dissipation. Thanks for that, but just want to clarify where do I put the resistor?


When I replace it with a BC, the circuit doesn’t work at all. 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. What type of voltage booster circuit is this? 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.

Vce would be much higher than 1. This is from 2SC datasheet: I have short-term access to another C – putting that in the circuit works just fine, so I know the transistor is the issue. But you can see that in some situations there are differences between BC and 2SC
