Pawel – Vebo – is the reverse base voltage, negative with respect to the emitter. The out leg that goes to the speaker doesn’t ever show any voltage, yet its leg that goes to the controller dattasheet different voltage drops I assume that’s the controller “playing” music.

There is a single traneistor, splitting to two circuits, one for diode lights, and another one to a speaker. Sign up or log in Sign up using Google. Nearly all transistors that are labeled according to the Japanese standard JIS lack the leading “2S”. Now, I really don’t know much about this, but really wanna fix that toy: And also, how do I tell that it would open when the base-emitter voltage transiwtor, not when it will be applied?

2SC Bipolar NPN Transistor Pinout, Features, Equivalent & Datasheet

Thank you for all your help, support, and explanations: This is always low, around 5V. You apply the 3V via a resistor which takes care of the voltage difference. There is absolutely no markings on this thing, and it has three legs and black solid body.

On the other hand, they say Vebo is 5V max If so, and I were to order a replacement from, say RadioShack, how would I find one that would work? The way it broke, as it’s there is no sound.

It very much looks like this: I believe the transistor for the speaker circuit just broke IMO, sitting an hour in rain would do it. I was probing both the transistors to see what’s going on when a toy is “activated”. See here page one for LVceo and some other relevant terms.

LVceo means – the minimal collector-emitter voltage to cause a break down is 50V, right? 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.

C Datasheet – Vcbo=60V, A, NPN Transistor

C P73C Ask Question. I’m trying to fix tranisstor little electronic toy. But, the only things I see on this transistor again, I don’t know what is it, reallyare: You need to do some basic reading on transistor parameters. I’m sorry, this is confusing: Or I don’t understand what “LVceo: It looks a lot like a 2SCwhose TO92 packaging matches the image you posted. Pawel Veselov 1 5.

Umm, datasheett don’t think 2SC is a little high voltage for battery operated?

Then the spec for 2SC says: 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. For transisror, 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. All right, so just to settle LVceo – 50V min.

C the first line, and P73C on the second line. And what’s with the P73C part?
