What type of voltage booster circuit is this? Sign up or log in Sign up using Google.

I have short-term access to another C – putting that in the circuit works just fine, so I know the transistor is the issue. The switching transistor shouldn’t go into breakdown. The BC got kind of warm, and didn’t work. So power dissipation would be mW, which is above maximum allowed power dissipation.

Email Required, but never shown. 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 have a circuit in which the C aka 2SC transistor failed after many datasheet.

Well, it’s whether excessive base current, or excessive product of Ic x Vce. Suitable replacement for 2SC transistor?

This is from BC datasheet: Adding schematic to show what I mean: How do you know that your transistor is the only problem in your circuit? Base current is not a problem, it is limited by R to 4.

Hi, Attila, thanks so much for prompt reply. Attila Kinali 1, 1 9. This would severely limit the lifetime of an already stressed component.

I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means. Post as a guest Name. Another relevant difference could be in hFE.

Can you clarify position of additional 10R resistor? This is from 2SC datasheet: BC hFE from to It depends on your batch. My previous, datasheet related question is here: 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.

Home Questions Tags Users Unanswered. There are huge differences: Now look in the datasheets to compare those two transistors what is the Vce for such current. Hence a load at its emitter datasyeet collector can cause it to have a negative impedance at its base. Sign up using Facebook. 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.

It is off the chart, it is a bad sign for this situation. Is it possible that there is another problem which caused your transistor to fail and which makes your new transistor hot? Vce would be much higher than 1.
