Put them up on Ebay and let them take them off your hands...some pack rat will want them.

Yeah, I could do that.

You could see if aeri inc (aeri.com) is interested in purchasing them, if they are new/unused.

They specialize in finding and selling old transistors. worldwide.

If nobody can find a datasheet for these, they aint worth a squirt.

They are most likely counterfeit, the Motorola symbol is not correct.

Searching the Motorola archives indicates they never produced this part number.

 

[WOPL Sniffer]

Have you seen the Motorola symbol from the 40's or 50's? It wouldn't make sense to counterfeit a transistor they never made. If the Chinee were going to waste time and money faking it, they would use a common part number.

 

[Hexis22]

Yup, worked at Motorola for over 20 years and seen a lot of crazy Chinese shit with fake M symbols.

In the trash they go

And they do. A common Chinese knock off is all the fake 15024s on ebay

They are showing 1985 date codes, if you believe that. I would say it's not very likely they are counterfeit. Probably an OEM's part number. I have a late 70's D.A.T.A. book for bipolar transistors I can check in a few days.

Don't bother Don, they went to recycle. Time is money.......
