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.
C Transistor – Transistor – Electronic Component
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 transisstor I assume that’s the controller “playing” music. 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 one available.
Email Required, but never shown. There is a transistor or I think it is for each circuit.

Umm, you don’t think 2SC is a little high voltage for battery operated? You apply the 3V via a resistor which takes care of the voltage difference. C P73C Ask Question. All right, so just to settle LVceo – 50V min.
And what’s with the P73C part?
The way it broke, as it’s there is no sound. Then the spec for 2SC says: And also, how do I tell that it would open when the base-emitter voltage drops, not when it will be applied? Sign up using Facebook. On the other hand, they say Dstasheet is 5V max Sign up using Email and Password.
I believe the transistor for the speaker circuit just broke IMO, sitting an hour in rain would do it. I trsnsistor probing both the transistors to see what’s going on when a toy is “activated”.

It’s really not much, 8 buttons, you push one, the lights go on, and a little melody plays. Nearly all transistors that are labeled according to the Japanese standard JIS lack the leading “2S”. It very much looks like this: But, the only things I see on this transistor again, I don’t know what is it, reallyare: Sign up or log in Sign up using Google.
See here page one for LVceo and some other relevant terms. You need to do some basic reading on dataxheet parameters. I’m trying to fix this little electronic toy. Pawel – Vebo – is the reverse base voltage, negative with respect to the emitter. Dormant, controller leg has the same voltage that is coming from the battery, and the “out” leg has nothing on it.

Post as a guest Name. If so, and I were to order a replacement from, say RadioShack, how would I find one that would work? For each, one right leg is straight to the batteries, the dxtasheet 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.
