For each, one right leg is straight to the batteries, the adtasheet left leg is to the chip through a resistorand the third one middle is to the outlet from one it’s to the speaker and from another it’s to lights. Now, I really don’t know much about this, but really wanna fix that toy: When the button is pushed, the voltage on the controller leg drops a volt or so, and the “out” leg starts showing some for lights.

In most applications not relevant.

I was able to replace this transistor with 2N I should’ve been more careful picking the replacement that had the same order of pins, but hey, this was the cheapest datashest available.

I believe the transistor for the speaker circuit just broke IMO, sitting an hour in rain would do it.


All right, so just to settle LVceo – 50V min. The out leg that goes to the speaker doesn’t ever show any voltage, yet its leg that goes to the controller shows different voltage drops I assume that’s the controller “playing” music.

C945 Transistor

I’m trying to fix this little electronic toy. C the first line, and P73C on the second line.

Pawel – Vebo – is the reverse base voltage, negative with respect to the emitter. Nearly all transistors that are labeled according to the Japanese standard JIS lack the leading “2S”. You apply the 3V via a resistor which takes care datasheett the voltage difference.

Then the spec for 2SC says: Pawel Veselov 1 5. But, the only things I see on this transistor again, I don’t know datasheft is it, really vatasheet, are: There is absolutely no markings on this thing, and it has three legs and black solid body.

There is a single controller, splitting to two circuits, one for diode lights, and another one to a speaker. On the other hand, they say Vebo is 5V max Umm, you don’t transistoor 2SC is a little high voltage for battery operated? See here page one for LVceo and some other relevant terms. This is always low, around 5V. Renan 4, 2 21 If so, and I were to order a replacement from, say RadioShack, how would I find one that would work? It looks a lot like a 2SCwhose TO92 packaging matches the image you posted.

There is a transistor or I think it is for each circuit. Dormant, controller leg has the same voltage that is coming from the battery, and the “out” leg has nothing on it. LVceo means – the minimal collector-emitter voltage to cause a break down is 50V, right?
