But you can see that in some situations there are differences between BC and 2SC BC doesn’t seem suitable Ask Question.

2SC Datasheet(PDF) – NEC

Vce would be much higher than 1. Post as a guest Name. It would take too much space to explain the exact datasheeet here, but the gist is, the transistor acts as an impedance conversion element at high frequencies due to beta being frequency dependent.

It depends on your batch. The switching transistor shouldn’t go into breakdown.

Another relevant difference could be in hFE. Sign up using Facebook. So power dissipation would be mW, which is above maximum allowed power dissipation. So, is there something ‘special’ about datasheet C trannies?

This is being used in a flyback circuit, which switches at approx ummm kHz or so. But it will be lower, say it is mA. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Sign up or log in Sign up using Google.

Email Required, but never shown. What could cause transistor to overheat? Sign up using Email and Password. This is your circuit: Hi, Attila, thanks so much for prompt reply.


This is from BC datasheet: BC hFE from to What type of voltage booster circuit is this? I have short-term access to another C – putting that in the circuit works just fine, so I know the transistor is the issue. Attila Kinali 1, 1 9. Can you clarify position of additional 10R resistor?

I Googled about, and tried to replace it with a BC This is from 2SC datasheet: Adding schematic to show what I mean: The BC got kind of warm, and didn’t work.

It is off the chart, it is a bad sign for this situation. There are huge differences: Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine. I have a circuit in which the C aka 2SC transistor failed after many years. I do not say your circuit is drawing mA, peaks could be higher or datassheet.

So, transistor could overheat by high Vce or Ic. Chupacabras 3, 2 11 Base current is not a problem, it is limited by R to 4. Home Questions Tags Users Unanswered. When I replace it with a BC, the circuit doesn’t work at all. I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means. Hence a load at its emitter or collector can cause it to have a negative impedance at its base.

Thanks for that, but just want to clarify where do I put the resistor? The datashet resistor dampens this oscillation. Well, it’s whether excessive base current, or excessive product of Ic x Vce. Is it possible that there is another problem which caused your transistor to fail and which makes your new transistor hot?

My previous, sort-of related question is here: Now look in the datasheets to compare those two transistors datawheet is the Vce for such current. If not, you have to take out a good oscilloscope and look at the dtaasheet. 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.

Thanks, any help appreciated! How do you know that your transistor is the only problem in your circuit? This dataheet severely limit the lifetime of an already stressed component. Suitable replacement for 2SC transistor?
