Another transister question

[scotts530]

I have a phoenix gold amp that uses 4 TIP36CO and 4 TIP35CO for the output transisters. My question is when I look the transisters up both of them share the same data sheet so are they the exact same or what?

No, they're not exactly the same, they're eachother's complement.
TIP35 = NPN
TIP36 = PNP.

Complementary devices are usually both in the same datasheet.

they are complementary transistors, TIP35 is NPN and TIP36 is PNP. Apart from some small differences in switching times and current gain they have similar voltage and current specifications.

Does anyone know what the CO means at the end of the part number is that important

"C" is the 100 volt grade. A=60V rated, B=80. If your supply is anywhere near 100V use the C. "O" is the beta range. Definitely match them if you're paralleling, try to match the 35 and 36's. R= the low end of the distribution, O= mid values, and Y= the high end (usually).

As long as you use the TIP35C and TIP36C from a reputable manufacturer, the replacements will work. When ordering, make sure that they transistors are in the same style case. The TIP35/36 come in several different case styles and not all will work with all clamping systems.
