I am looking for any data, substitute, or availability on these transistors. The 7279 is an NPN and the 7278 is a PNP silicon as best I can tell. They are both TO-220 type cases with an 'EBC' pin out.

The application uses 4 of these, with a 36.5 ohm resistor in series with the emitter, all in parallel, to make up a TO-66 type package transistor substitute for each of tne PNP and NPN application.

Thanks in advance.
