2SC Datasheet PDF –

When I replace it with a BC, the circuit doesn’t work at all. Home Questions Tags Users Unanswered. BC hFE from dahasheet 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.

Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine. Email Required, but never shown. What could cause transistor to overheat? Is it possible that there is another problem which caused your transistor to fail and which makes your new transistor hot?

But it will be lower, say it is mA. So, transistor could overheat by high Vce or Ic. It is datasneet the chart, it is a bad sign for this situation.


I have a circuit in which the C aka 2SC transistor failed after many years. Vce would be much higher than 1. Another relevant difference could be in hFE. It depends on your batch.

This is being used in a flyback circuit, which switches at approx ummm kHz or so. I have short-term access to another C – putting that in the circuit works just fine, so I know the transistor is the issue. Now look in the datasheets to compare those two transistors what is the Vce for such current.

What type of voltage booster circuit is this? The additional resistor dampens this oscillation.

This is from BC datasheet: This would severely limit the lifetime of an already stressed component. The BC got kind of warm, and didn’t work. How do you know that your transistor is the only problem in your circuit? This is your circuit: My previous, sort-of related question is here: Chupacabras 3, 2 11 But you can see that in some situations there are differences between BC and 2SC So power dissipation would be mW, which is above maximum allowed power dissipation.

There are huge differences: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. I Googled about, and tried to replace it with a BC This is from 2SC datasheet: Sign up or log in Sign up using Google.


Hi, Attila, thanks so much for prompt reply. I do not say your circuit is drawing mA, peaks could be higher or lower. Well, it’s whether excessive base current, or excessive product of Ic x Vce. Thanks, any help appreciated! Hence a load at its emitter or collector can cause it to have a negative impedance at its base.

I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means. So, is there something ‘special’ about the C trannies?

Sign datadheet using Facebook. 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. BC doesn’t seem suitable Ask Question.

Suitable replacement for 2SC transistor?

Adding schematic to show what I mean: Base current is not a problem, it is limited by R to 4.
