Some of the answers I’ve got tell me this is 2SC, which is then, according to http: Now, I really don’t know much about this, but really wanna fix that toy: I’m sorry, this is confusing: 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.

There is absolutely no markings on this thing, and it has three legs and black solid body.

For each, one right leg is straight to the batteries, the second left leg is to the chip through a resistorand the third one middle dataaheet to the outlet from one it’s to the speaker and from another it’s to lights.

See here page one for LVceo and some other relevant terms. Post as a guest Name.

I’m trying to fix this little electronic toy. Renan 4, 2 21 This is always low, around 5V.

If so, and I were to order a replacement from, say RadioShack, how would I find one that would work? Sign up using Facebook. All right, so just to settle LVceo – 50V min.

I was probing both the transistors to see what’s going on when a toy is “activated”. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Then the spec for 2SC says: The way it broke, as it’s there is no sound. And also, how do I tell transishor it would open when the base-emitter voltage drops, not when it will be applied? There is a transistor or I think it is for each circuit. Or I don’t understand what “LVceo: Umm, you don’t think 2SC is a little high voltage for battery operated? Pawel Veselov 1 5.

And what’s with the P73C part? Thank you for all your help, support, and explanations: LVceo means – the minimal collector-emitter voltage to cause a break down is 50V, right?

Dormant, controller leg has the same voltage that is coming from the battery, and the “out” leg has nothing on it. But, the only things I see trandistor this transistor again, I don’t know what is it, reallyare: It very much looks like this: It’s really not much, 8 buttons, you push one, the lights go on, and a little melody plays.

Pawel – Vebo – is the reverse base voltage, negative with respect to the emitter.

I believe the transistor for the speaker circuit just broke IMO, sitting an hour in rain would do it. You apply the 3V via a resistor which takes care of the voltage difference. On trahsistor other hand, they say Vebo is 5V max Sign up using Email and Password.

C the first line, and P73C on the second line. When the button is pushed, the voltage on the eatasheet leg drops a volt or so, and the “out” leg starts showing some for lights.

Email Required, but never shown. The out leg that goes to the speaker doesn’t ever show any voltage, yet its leg that goes to the controller transitor different voltage drops I assume that’s the controller “playing” music.

There is a single controller, splitting to two circuits, one for diode lights, and another one to a speaker.
