Hello,

Can someone help me identify this Motorola transistor..

I drew exactly how it looks

I think the first line is when the it was manufactured not sure

I need to find a replacement..

Many transistors are printed with 'house codes' that only mean something to the company buying them from Motorola. It's almost impossible to find their real part numbers.

Are you sure it's a transistor? Motorola usually use MJE as the letters in part numbers but sometimes only print the digits so it could be an MJE906 although I can't find any reference to such a device being made. If it's an SCR, they use the letters MCR.

Can you show a photograph or tell us it's approximate dimensions and say whether it has a mounting hole in it or an exposed metal area on one side.

Here is the actual picture

I used a Multi meter to check resistance and polairty.
I believe it to be PNP

24.6 mega ohm 1 - 2
23.6 Mega ohm 3 - 2

2 is base

Thanks, from your original drawing it wasn't possible to telll if it was a power device or a small signal device. It looks like a TO-92 pagage and from your tests I would say there is a good chance it's a 2N3906.

It is TO-226AE - 1W TO-92. Looking through an old Motorola small signal devices databook from the 1980s I cannot find anything in that package with xx906 part number. Also they don't show the abbreviations that they make on the package so identification is going to be guesswork.

:( 2N3906 may burn out fast due to the draw.. it's 12.3v
