I got those things, but what function may they have?

[Geir Klemetsen]

The first thing (don't remember where it come from or it's age) looks very
similat to an regular transistor. The cap is almost an TO-202 but some
smaller. The front side is marked: "c106n RCA HH 8419".

Another one has a TO-202 case, and is stamped "f2r5g"

Just another one that has an unknown name: "frp1610" and the case is TO-220

A gray-colored one named "sf3j41" that also seems like a power-transistor.
Case to-220.

Had been great if I got datasheets to any (or all) of them. Cannot find any
on the net.

By the way: I also has a dousin of transistors marked with "RCA" and some
numbers after or before. Is there any chance to find data on them on the net
(e.g. those's name is realy something else)? For example, Transistors market
"SC" followed by three or four digits, I assume it's real name is 2SC + the
same number.

The C106 is a sensitive gate SCR, 4 amps. (Originally from GE, but GE
doesn't make semicondutors any more). You sure about the "n"? My RCA
datasheet only goes up to M which is 700 volts. (The letter suffix
giving the voltage rating isn't in any order, F was lower voltage than
A). A lot of companies made it, TI, and Motorola, and I think Teccor.
It will be a family data sheet. Try On Semi, or Teccor.

Old RCA transistors had part numbers with 5 decimal digits, like
40392. Sometimes they're in catalogs and parts lists as RCA40392.
