Transistors identification
I found these transistors but could not get information about them, does anyone know?Motorola 1854-1220 and 1854-0922.

Re: Transistors identification
Probably an internal manufacturer part number.
Manufacturers have special parts custom made by semiconductor companies (if they need a sufficient quantity that is) and they can have them printed with whatever part number they want.
Like the DNA1001 and 1002 ICs on the original Xbox PSUs. No datasheets or info available anywhere.Last edited by Krankshaft; 07-18-2011, 11:00 AM.Elements of the past and the future combining to make something not quite as good as either. -
Re: Transistors identification
OEM part numbers that you'll never find. Test them and if they are good, use them for a projects like a power supply regulator.Is it plugged in?Comment

Re: Transistors identification
Those look like H/P part numbers but they don't show on the cross ref. charts. What are these out of, if I may ask?Comment
