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 on this transistor again, I don’t know what is it, reallyare: If so, and I were to order a replacement from, say RadioShack, how would I find one that would datawheet Or I don’t understand what “LVceo: For each, one right leg is straight to the batteries, the second left leg is to the transitsor through a resistorand the third one middle is to the outlet from one it’s to the speaker and from another it’s datasueet lights.

C P73C Ask Question. I was able to replace this transistor with 2N C954 should’ve been more careful picking the replacement that had the same order of pins, but hey, this was the cheapest one available.

The way it broke, as it’s there is no sound. Post as a guest Name. Some of the answers I’ve got tell me this is 2SC, which is then, according to http: Home Questions Tags Users Unanswered.

And what’s with the P73C part? 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.

Thank you for all your help, support, and explanations: Renan 4, 2 21 It looks a lot like a 2SCwhose TO92 packaging matches the image you posted.

LVceo means – the minimal collector-emitter voltage to cause a break down is 50V, right? You need to do some basic reading on transistor parameters. Now, I really don’t know much about this, but really wanna fix that toy: I believe the transistor for the speaker circuit just broke IMO, sitting an hour in rain would do it.

And also, how do I tell that it would open when the base-emitter voltage drops, not when it will be applied? I’m trying to fix this little electronic toy. On the other hand, they say Vebo is 5V max There is a transistor or I think it is for each circuit.

It’s really not much, 8 buttons, you push one, the lights go on, and a little melody plays. Then the spec for 2SC says: C the first line, and P73C on the second line. This is always low, around 5V. Nearly all transistors that are labeled according to the Japanese standard JIS lack the leading “2S”.

There is absolutely no markings on this thing, and it has three legs and black solid body. Email Required, but never shown. When the button is pushed, the voltage on the controller leg drops a volt or so, and the “out” leg starts showing some for c954.

The out leg that goes to the speaker doesn’t ever show any voltage, yet its leg that goes transitsor the controller shows different voltage drops I assume that’s the controller “playing” music. All right, so just to settle LVceo – 50V min. Umm, you don’t think 2SC is a little high voltage for battery operated?

It very much looks like this: Sign up using Facebook.

I’m sorry, this is confusing: You apply the 3V via a resistor which takes care of the voltage difference. Sign up or log in Sign up using Google. Datashheet most applications not relevant.

There is a single controller, splitting to two circuits, one for diode lights, and another one to a speaker. See here page one for LVceo and some other relevant terms. Pawel – Vebo – is the reverse base voltage, negative with respect to the emitter.
