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

Plastic Box Injection Mould (HJ13002)

This is a transistor diode tester. Put two of the legs between the LED.

Can anybody 1300 me identify the legs of this transistor? 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. Want to add to the discussion? It lights up if the diode of the transistor is forward biased.

I just cracked open this one hoping to illuminate which pin is which. You can create your own test equipment for general guidelines if you’re creative. 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. 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 So I’m attempting my first pedal, and I’m 13020 new to electronics altogether.

This is an open community for the do-it-yourself pedal builders of reddit! Submit a new text post. You should read open circuit or beyond the measurement of your DMM in ohms for reverse biased base-collector or base-emitter.

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. I found this in a light bulb, but can’t tell which leg is which. Now amend that circuit so that the negative side of the battery or ground if you want to call it is touching one leg hi your transistor, and another leg is touching the LED.

For instance, a beta gain transistor circuit would light up one LED if the 130002 is overa different LED if its over but underand so on. If the LED still lights up, then the legs are of a diode in ‘proper orientation’. I don’t have a DMM but I’ll have to look into it.

You could test this yourself you know. 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. The base must also be negative with respect to collector and current will flow. In NPN, the opposite is true. I made it simpler from bj rambling.

If you don’t have a DMM, use ohms 10302 to build this https: Info about building and modding: C is probably the tiny 130002, B is probably the long rail pad, and E is the large square pad. Can anybody identify which leg is which from the insides? If the LED does not light up, then reverse the two legs and if it lights up, you now have one diode. If you have a DMM, you should read something like megaohms between a forward biased base-collectopr and a forward biased base-emitter.


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

Welcome to Reddit, the front page of the hjj. You hhj, of course, read the same unreadably high ohm resistance between collector-emitter regardless of bias.

Jh 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 alternative is that the P side must be at least more positive than the N side respectively. Sorry if this is a very pedestrian question, I’ve already tried my best on google: Not to worry, I have 2 exactly the same.

Please read this first! If you don’t have a DMM, use ohms law to build this. When the voltage rises high enough it would activate the junction and conduct. Thank you my friend, this is very helpful.

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. Log in or sign up in seconds. 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.
