If your meter has a transistor tester – you could simply try all of the six possible pin configurations – in both polarities. The emitter of an NPN transistor is connected to – or towards – the negative line.

These diodes will conduct – when the red meter lead is connected to a “P” terminal. 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.

And the LED will light. There are huge differences: Hence a load at its emitter or collector can cause it to have a negative impedance at its base. So, transistor could overheat by high Vce or Ic.


So, is there something ‘special’ about the C trannies? If the LED glows – even dimly – the collector and emitter are connected the wrong way round. Post as a guest Name.

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. Next – wet the tip of your finger with the tip of your tongue. The small arrowhead – in the symbol – indicates the direction of the base current. But you can see that in some tranistor there are differences between Tfansistor and 2SC This is from BC datasheet: So power dissipation would be mW, which is above maximum allowed power dissipation.

Home Questions Tags Users Unanswered. The switching transistor shouldn’t go into breakdown. Try transistpr six possible pin configurations. I Googled about, and tried to replace it with a BC If not, you have to take out a good oscilloscope and look datashet the waveforms. And plug in your transistor. Sign up or log in Sign up using Google. Email Required, but never shown.

There is an element of trial and error involved. And use your wet fingertip to join the collector to the base.

My previous, sort-of related question is here: BC hFE from to I do not say your circuit is drawing mA, peaks could be higher or lower. But since we’re dealing with a limited number of variables – the task is not too daunting.

If your transistor is working properly – transsistor connected correctly – the moisture will supply sufficient base current to switch the transistor on. It is off the chart, it is a bad sign for this situation.

BC doesn’t seem suitable Ask Question. Base current is not a problem, it is tranwistor by R to 4. Use trial and error to position the other two pins. There are only three leads – collector – base – and emitter. Hi, Attila, thanks so much for prompt reply. Since we’re going to use the meter to identify the polarity of the transistor – the polarity of the meter leads is crucial. This is being used in a flyback circuit, which switches at approx ummm kHz or so.

And its collector is connected to – or towards – the positive line. The additional resistor dampens this oscillation. The BC got kind of warm, and didn’t work. I have seen them referred to as ‘switching’ transistors somewhere, I don’t know what that specially means.

Suitable replacement for 2SC transistor? You already know where the base pin should go. What could cause transistor to overheat?

The collector of a PNP transistor is connected to – or towards – the negative line. I have short-term access to another C – putting that in the circuit works just fine, so I know the transistor is the issue.

You can still use these two circuits to identify the polarity of your transistor – and its pin configuration.
