I’m trying to fix this little electronic toy.

C Transistor – Transistor – Electronic Component

I believe the transitsor for the speaker circuit just broke IMO, sitting an hour in rain would do it. Some of the answers I’ve got tell me this is 2SC, which is then, according transistpr http: By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

LVceo means – the minimal collector-emitter voltage to cause a break down is 50V, right? Sign up using Email and Password.

Thank you for all your help, support, and explanations: It looks a lot like a 2SCwhose TO92 packaging matches the image you posted. Then the spec for tfansistor says: 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 is to the outlet from one it’s to the speaker and from another it’s to lights. See here page one for LVceo and tfansistor other relevant terms. Umm, you don’t think 2SC is a little high voltage for battery operated?

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

On the other hand, they say Vebo is 5V max I’m sorry, this is confusing: This is always low, around 5V. C P73C Ask Question. Nearly all transistors that are labeled according to the Japanese standard JIS lack the leading “2S”. 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.

You apply the 3V via a resistor which takes care of the voltage difference. Home Questions Tags Users Unanswered. Renan 4, 2 21 In most applications not relevant.

Tranwistor need to do some basic reading on transistor parameters. Post as a guest Name.

It’s really not much, 8 buttons, you push one, the lights go on, and a little melody plays. I was probing both the transistors to see what’s going on when a toy is “activated”. But, the only things I see on this transistor again, I don’t know what is it, reallyare: 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. There is absolutely no markings on this thing, and it has three legs and black solid body. Sign up using Facebook.


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. All right, so just to settle LVceo – 50V min.

Now, I really don’t know much about this, but really wanna fix that toy: It very much looks like this: Pawel Veselov 1 5. And what’s with the P73C part? There is a single controller, splitting to two circuits, one for diode lights, and another one to a speaker. 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.

The way it broke, as it’s there is no sound.

If so, and I were to order a replacement catasheet, say RadioShack, how would I find one that would work? C the first line, and P73C on the second line. And also, how do I tell that it would open when the base-emitter voltage drops, not when it will be applied?

Or I don’t understand what “LVceo:
