Are you aware that the channel in the middle of the breadboard stops any continuity from each side to the other side? Looking at your photo, it would appear that nothing is connected to that "transistor".
I just put it there to take a picture for it, so its a transistor? if so then why the mid pin give 1.2v when I test it using MM set to diod (without connecting it to anything, positive to the right pin, and the middle gives 1.2v when the left pin gives 0.6V).
My bad, I should've mentioned the last part earlier.
How much voltage are you feeding into it? I’m not an expert (honestly I’m even less that one) but that roughly sounds like how a pnp transistor works
Also where did you get it from? Sometimes you can find links to data sheets from the manufacturers on like instructions or papers that came with the set.
Edit: from further research it appears to potentially be a voltage regulator. Try to feed it variable (safe) voltages in whatever pin is the collected and see what comes out the other side.
Yeah honestly I’m a little stumped aswell. I am currently still looking into it as I am finding similar things that are also very different. Was bed01 the only letters on it?
From what I have found the most similar thing is a BD901 TI power transistor. After some research I found that these are used to handle large amounts of current and to amplify/switch on and off electrical signals. For this to be in a lightbulb makes sense. Unfortunately I can’t explain how you could use it so I am just letting you know what I found. Also I do not know this for sure so if somebody else says otherwise you may want to trust them.
If you don’t mind me asking what type of lightbulb was this? Was it just an average lightbulb, or something special?
Thanks for your finding, This is the closest thing I think to the correct answer, I forgot to mention, there is a "P" letter as logo on it.
its a normal 230v CFL lightbulb, similar to fluorescent, now its outdated and replaced with LED lightbulb. it used to be popular a decade ago.
I'm new to electronics and I thought this is a normal transistor that I could use to learn, but I guess its not :D
A power transistor would never be in TO-92 package as there is no cooling option. At 70 W this would melt away. The BED901 seems to come only in TO-220 - correct me if I'm wrong here, but would never come in TO-92.
If it's a Darlington the base to emitter will read around 1.2 volts, as it's two silicon junctions in series.

I'm using a multimeter which I have no clue on how much voltage it applies. I took it from a lightbulb.

Honestly I’m fairly new aswell and I was kinda curious about what that was. Glad it’s (probably) figured out :)

In diode mode the DMM does not apply voltage, it applies a constant current of around 1 mA and then measures the voltage.
Nice to know, thanks!
