A1507 PNP switching transistor

Might be a 2SA1507.... The Japs marked them with just a A1507

2 = 2 + 1 pins, S = Silicon A = PNP.

Here's a data sheet on the web

Does it fit the package you have?

Joe

Yes, that's the one Joe. Any idea where to source it (or an equivalent) from in Aus? Thanks.

**WES Components don't have them, so you may need to look for a substitute. What specs do you need?

** The specs on that BJT are exceptional - he will need the original type.

BTW:

Watch out for TO3P ( as well as TO3) fakes at WES - bought a couple of Toshiba 2SA1941s that were anything but genuine.

**Tell me about it! I'm starting to lose patience with WES. One of my colleagues got stuck with fake MOSFETs (for TV repair work). Two different types too.

More recently, I ordered and received a couple of RCA-RCA leads. Part #OFC608. They are (or more correctly, WERE) a bloody nice product. Polyethylene centre conductor insulation, plenty of conductors, aluminium AND copper braid shielding, nice looking and well bonded to the RCA connectors. In about 6 years, I've never had a problem with them. I've installed them into countless customer's systems. They are (or were) FAR superior to WES's next lower grade product. Although the cheaper product had fancy looking gold plated connectors and a pretty blue sheath, it was just bog-standard, crappy RCA cable. Shitty PVC insulation, around double the capacitance and crappy shielding.

Anyhoo, one of the latest cables developed a fault as soon as I installed it. Curious, I stripped the cable apart. I found the older, cheaper cable, with a fancy light blue jacket wrapped around the whole shebang.

I am now attempting to track down all the cables I've sold in recent times. I'll be sending them back to WES and demanding proper replacements.

Are the fakes branded as anything in particular usually or do the use any manufacturers markings? Ever had any bad ST branded TO3s?

** Ha, ha - so YOU got caught with the substitution as well.

The original WES OFC cables were a form of RF coax - 22pF per foot.

Now, they are poorly shielded crap with 220pF per foot.

** Lotsa luck.

** The fakes are made to look as close as possible to genuine, brand name devices. ** I do try not to buy fakes.

There is no reason why the ST logo would not be used by counterfeiters - nearly very other famous logo has been.

Thanks Trevor and Phil. I appreciate you working together to provide me with the useful lead/info. I think I may need the original (though, through some searching, I might get away with 2SD600 or 2SA1209 - though I can't locate a source from them either).

** 2SD600 = NPN, 120V, 1A, 130MHz 2SA1209 = PNP ....... 2SA1507 = PNP ......

??????????????

...... Phil

**As Phil has stated, the fakes are found in most (all?) quality brand names. The ones I have found usually can be detected by some (very slight) physical differences. Mind you: those differences are very hard to pick. Further: The foregoing does not suggest that ALL fakes are physically distinguishable from the originals.

Thanks Phil, My bad. I think that should read 2SB631.

Excellent, thanks for the lead Greg.

Thanks Franc, good find! I can't seem to find a web site for them. Guess I'll just call.

Go direct or via Oz agent X-On

Star Components have been around for more than ten years. I've dealt with them in the past. I've even had a visit from their sales rep who left me several catalogues. They are located in Toongabbie.

I don't know why they don't have an Internet presence, but they supply AV parts (VCR, TV, CD/DVD, manuals), semiconductors, passives, etc. They are somewhat like WES in that they cater to the service industry, but their range is much smaller.
