Re: Darlington Transistor Generic Number


Hi Gary,
Yes there is a database of Tek semiconductors.
You need to discover the amazing resource we have called Tekwiki.

If you search for Common Design Parts Catalogs you will find a whole bunch of them. In your case you would want the Semiconductor one this time. It lists Tek semiconductors lots of different ways, including by manufacturer's part number, specifications, etc.
Have fun.

Does anyone know the generic part number and manufacturer for the
Tektronix part number 151-0405-00? It is an NPN Silicon darlington
transistor in a TO-126 package. It is used in the power supply of the
Tektronix Model 577 curve tracer. Also, is there a database of
cross-referenced Tek part numbers?
