Put two of the legs between the LED. I made it simpler from the rambling. When the voltage rises high enough it would activate the junction and conduct.

You should read open circuit or beyond the measurement of your DMM in ohms for reverse biased base-collector or base-emitter. I don’t have a DMM but I’ll have to look into it.

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. Transistors function in their active region as class Jh amplifiers thanks to the nj being reverse biased while the base-emitter is forward biased.

If you have a DMM, you should read something like megaohms between a forward biased base-collectopr and a forward biased base-emitter. 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.

Can anybody help me identify the legs of this transistor? : diypedals

If you don’t have a DMM, use ohms law to build this. 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 CD Submit a new link. With a DMM, you can 10302 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.

C is probably the tiny pad, B is probably the long rail pad, and E is the large square pad. This is an open community for the do-it-yourself pedal builders of reddit! If the LED still lights up, then the legs are of a diode in ‘proper orientation’. Submit a new text post. FYI this is a high voltage transistor designed for switching operation, very commonly found in compact fluorescent lamps.

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.

You can create your own test equipment for general guidelines if you’re creative. Can anybody identify which leg is which from the insides?

Sorry if this is a very pedestrian question, I’ve already tried my best on google: The alternative is that the P side must be at least more positive than the N side respectively. Log in or sign up in seconds. I found this 130002 a light bulb, but can’t tell which leg is which. It lights up if the diode of the transistor is forward biased. This is a transistor diode tester.

Thank you my friend, this is very helpful. The base must also be negative with respect to collector and current will flow.

But I’m not positive it was the right datasheet. You could test this yourself you know.

I know the Base is typically in the middle, but i googled yj numbers from the face,HJ, B1 and found a datasheet for the HJ Transistor, which said the Base was the leftmost leg. Please read this first!

You will, of course, read the same unreadably high ohm resistance between collector-emitter regardless of bias. Basically, you create a circuit that needs the transistor to behave with X amount of gain otherwise the current is too weak to light the 1302.

If you don’t have a DMM, use ohms law to build this https: Not to worry, I have 2 exactly the same.

HJ Datasheet –

Can anybody help me identify the legs of this transistor? For instance, a beta gain transistor circuit would light up one Gj if the gain is overa different LED if its over but underand so on. So Yj attempting my first pedal, and I’m totally new to electronics altogether. Then test the other two legs. If the LED does not light up, then reverse the two legs and if it lights up, you now have one diode. In NPN, the opposite is true. It’s dead, you need a new transistor.
