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

Not to worry, I have 2 exactly the same. Submit a new link. 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. Please read this jh

C is probably the tiny pad, B is probably the long rail pad, and E is the large square pad. 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.

Sorry if this is a very pedestrian question, I’ve already tried my best on google: It lights up if the diode of the transistor is forward biased. If you don’t have a DMM, use ohms law to build this https: 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.

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. 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.

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. It’s dead, you need a new transistor. But I’m not positive it was the right datasheet. The base must also be negative with respect to collector and current will flow. You will, of course, read the same unreadably high ohm resistance between collector-emitter regardless of bias.

Looking for troubleshooting help? When the voltage rises high enough it would activate the junction and conduct.

This is a transistor diode tester. Im going to assume the gj is the large pad, so the base is going to be one of the others, and the collector is obviously the last. Can anybody help me identify the legs of this transistor?

Thank you my friend, this is very helpful. FYI this is a high voltage transistor designed for switching operation, very commonly found in compact fluorescent lamps. Log in or sign up in seconds.

You can create your own test equipment for general guidelines if you’re creative. If you don’t have a DMM, use ohms law to build this.

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 nj leg is touching the LED. So I’m attempting my first pedal, and I’m totally new to electronics altogether. I made it simpler from the rambling. If the LED still lights up, then the legs are of a diode in ‘proper orientation’. Info about building and modding: 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.

I don’t have a DMM but I’ll have to look into it. I found this in a light bulb, but can’t tell which leg is which. Put two of the legs between the LED.
