In a PNP, the base is the N, so it must be negative with respect to the emitter and it will be biased and current will flow. Looking for troubleshooting help?

If the LED does not light up, then reverse the two legs and if it lights up, you now 31002 one diode. Doing so would actually improve your knowledge and and your soldering skill and get you some really cheap tools, although DMMs these days aren’t very expensive.

FYI this is a high voltage transistor designed for switching operation, very commonly found in compact fluorescent lamps. If you don’t have a DMM, use ohms law to build this.

In NPN, the opposite is true. If you don’t have a DMM, use ohms law to build this https: I just cracked open this one hoping to illuminate which pin is which.

For instance, a beta gain transistor circuit would light up one LED if the gain is overa different LED if its over but underand so on. But I’m not positive it was the right datasheet.

Not to worry, I have 2 exactly the same. Can anybody identify which leg is which from the insides? Use of this site constitutes acceptance of our User Agreement and Privacy Policy. Sorry if this is a very pedestrian question, I’ve already tried my best on google: Can anybody help me identify the legs of this transistor?

Please read this first!

Welcome to Reddit, the front page of the internet. Transistors function in their active region as class A amplifiers thanks to the base-collector being reverse biased while the base-emitter is forward biased. It’s dead, you need a new transistor. hhj

Submit a new text post. Now amend that circuit so that the negative side of the battery or ground if you want to call it is touching one leg of your transistor, and another leg is touching the LED. If the LED still lights up, then the legs are of a diode in ‘proper orientation’. I found this in a light bulb, but can’t tell which leg is which. Then test the other two legs.

The alternative is that the P side must be at least more positive than the N side respectively. Submit a new link. I made it simpler from the rambling.

If you have a DMM, you should read something like megaohms between a forward biased base-collectopr and a 130002 biased base-emitter. With a DMM, you can test the legs and each pair that has low resistance is a forward biased junction, any pair that has high resistance is a reverse biased junction. I don’t have a DMM but I’ll have to look into it. Im going to assume the emitter is the large pad, so the base is going to be one of the others, and the collector is obviously the last.

I know the Base is typically in the middle, but i googled the numbers from yj face,HJ, B1 and found a datasheet for yj HJ Transistor, which said the Base was the leftmost leg. So I’m attempting my first pedal, and I’m totally new to electronics altogether. Put two of the legs between the LED. You can create your own test equipment for general guidelines if you’re creative.

When the voltage rises high enough it would activate the junction and conduct. The silicon is normally bonded to the collector, which would match the ECB left to right, flat writing side facing you, pins facing downwards pinout of the Hhj Thank you my friend, this is very helpful.
