You will, of course, read the same unreadably high ohm resistance between collector-emitter regardless of bias. 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 know the Base is typically in the middle, but i googled the numbers from the face,HJ, B1 and found a datasheet for the HJ Transistor, which said the Base was the leftmost leg.

But I’m not positive it was the right datasheet. C is probably the tiny pad, B is probably the long rail pad, and E is the large square pad.

I made it simpler from the rambling. You should read open circuit or beyond the measurement of your DMM in ohms for reverse biased base-collector or base-emitter.

If the LED does not light up, then reverse the two legs and if it lights up, you now have one diode. If you don’t have gj DMM, use ohms law to build this https: 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.

I just cracked open this one hoping to illuminate which pin is which. Not to worry, I have 2 exactly the same. Then test the other two legs.

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. 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.

In NPN, the opposite is true. You could test this yourself you know. 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. 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 This is an open community for 10302 do-it-yourself pedal builders of reddit!

Sorry if this is a very pedestrian question, I’ve already tried my best on google: You can create your own test equipment for general guidelines if you’re creative. Put two of the legs between the LED.

If you have a DMM, you should read something like megaohms between a forward biased base-collectopr and a forward biased base-emitter. It’s dead, you need a new transistor. If you don’t have a DMM, use ohms law to build this. Thank you my friend, this is very helpful. Can anybody help me identify the legs of this transistor?

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. FYI this is a high voltage transistor designed for switching operation, very commonly found in compact fluorescent lamps. 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 LED.

When the voltage rises high enough it would activate the junction and conduct. Please read this first! Want to add to the discussion? The base must also be negative with respect to collector and current will flow. Can anybody identify which leg is which from the insides?

I found this in a light bulb, but can’t tell which leg is which.

It lights up if the diode of the transistor is forward biased. If the LED still lights up, then the legs are of a diode in ‘proper orientation’. Welcome to Reddit, the front page of the internet. So I’m attempting my first pedal, and I’m totally new to electronics altogether. 130002 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.
