Transistor General Purpose TO-92

This 2c2001 your circuit: So power dissipation would be mW, which is above maximum allowed power dissipation. Is it possible that there is 2c2001 problem which caused your transistor to fail and which makes your new transistor hot?

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.

What could cause transistor to overheat? Thanks, any 2sc2001 appreciated! There are huge differences: I Googled about, and tried to replace it with a BC Hence a load at its emitter or collector can cause it to have a negative impedance at its base. Can you clarify position of additional 10R resistor? Chupacabras 3, 2 11 Sign up using Email and Password.


What type of 2s2001 booster circuit is this?

Hi, Attila, thanks so much for prompt reply. Hi there Chupacabras, when I replace it with a good C the whole circuit works just fine.

Now look in the datasheets to compare those two transistors what is the Vce for such current. Well, it’s whether excessive base current, or excessive product of Ic x Vce.

This is from 2SC datasheet: This is being used in a 2xc2001 circuit, which switches at approx ummm kHz or so.

Another relevant difference could be in hFE. So, transistor could overheat by high Vce or Ic. Sign up or log in Sign up using Google. 2c2001 do you know that your transistor is the only problem in your circuit? This is from BC datasheet: 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.

But it will be lower, say it is mA. When I replace it with a BC, the circuit doesn’t 2scc2001 at all. Post as a guest Name. So, is there something ‘special’ about the C trannies? Email Required, but never shown. It depends on your batch. It is off the chart, it is a bad sign for this situation. The additional resistor dampens this oscillation. Sign up using Facebook. I have a circuit in which the C aka 2SC transistor failed after many years.


The switching dqtasheet shouldn’t go into breakdown. 2sc2001 previous, sort-of related question is here: I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means. If datashert, you have to take out a good oscilloscope and look at the waveforms.

Base current is not a problem, it is limited by R to 4. Home Questions Tags Users Unanswered. Attila Kinali 1, 1 9. BC hFE from to 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. I do not say your circuit is drawing mA, peaks could be higher or lower.

2SC datasheet, Pinout ,application circuits Transistor General Purpose TO

Suitable replacement for 2SC transistor? Vce would be much higher than 1. BC doesn’t seem suitable Ask Question. Adding schematic to show what I mean: The BC got kind of warm, and didn’t work.
