You'll find more info prefixing the numbers properly; ie RCA1C03,
RCA1C04, ETC.

I can forward data sheets from the RCA 1977 Power Devices data book,
if you're specific about devices of interest.

For just straight one-line data summaries, check out 'Tehnomagazin'

http://tinyurl.com/6k5fhd

This combines un-proofread data, stripped from TDTowers publications
and some DATA catalogs.... and is, in turn, currently mined by a
number of 'data-sheet server' web services.

The RCA prefix was what I needed, thanks

then eg
http://www.datasheetarchive.com/specsheet/RCA1C03.html

If anyone knows, presumably generically for RCA, what the C suffix (plus
other letters ?) mean would be useful for the archives of this thread,
presumably post production voltage bin ranges.


I've also saved
http://www.tehnomagazin.com/Transist...ables/transist
ors_Q,R,RCA,RCP,RE,RJH,RS,RT,RV.htm
to disc for future reference

I should have said my RCA transistor, thyristor & diode databook is 1969
(fallen apart and water/insect damaged but still useful)

Other RCA, like RCA29 and RCA30 with suffix letters
are like TI and A = 1.5 times basic non-suffix Vcb max
B = x2
C= x2.5

I cannot believe a 1C03 - C is 2.5 x 120V = 300 volt rating
in a circuit with rails + and -33 volt

Nigel,

From page 486 in the 1981 RCA Power Devices data book in my library:

"Silicon Transistors for Audio-Frequency Linear-Amplifier Applications"

RCA1C03 (NPN):
V(CBO) 120V
V(CEO) 100V
I(C) 4 amps
P(T) is 40 Watts with CASE temp at 25 decrees C.
F(T) 4 MHz
h(FE) 50-250


The RCA1C04 is the PNP compliment, specs the same except F(T)=5 MHz

The RCA1C012 (and compliment RCA1C013) are the same except the
V(CBO)=140V and the V(CEO)=120V. (They list these with and without the
'0' on the same page, so they might be called RCA1C12 and RCA1C13)

If you need the more detailed specs, let me know.

Any reference to what the suffix C means in
RCA1C03-C

Vcb max of 120V times 2.5 = 300 volt seems unlikely

The letter suffixes of TIPxx devices signify voltage groups,
increasing by 20V VCEO in each range, not a multiplier of a base
voltage rating. The RCAxx corresponding devices follow the same TIPxx
convention, to directly substitute for the TIP parts.

RCA1Axx, RCA1Bxx and RCA1Cxx devices, if given a dash suffix, are more
likely being graded for HFE, as voltage grading is already signified
by the xx part of the device ident. The gain group may be important in
matching quiescent bias loss of paralleled output drivers.

Grading parts for VCBO is pointless when dealing with linear audio
devices, as VCEO or VCES, SOArea and Rthjc will determine their
ruggedness in non-switching circuits driving reactive loads or single
faults. VCEO is always equal to, or less than VCBO.

The RCA house number data sheets refer to JEDEC part numbers for
device curves and test conditions.

Nigel,

There is no reference to any suffix on the data sheet I have. (I can
fax you a copy if you e-mail me with a fax number.) Also, I'm not aware
that RCA ever used a 'multiplier'. Texas Instruments did on some
devices (like the TIP-31/31A/31B/31C) but I'm not aware that the suffix
was a multiplier. The data sheet always listed the specific voltage for
each version.

Oh, I've got one of those (with thr 70W amp design that WEM used) albeit in
slightly less abused condition.

HH were well known for using 'house numbers'. The HH output transistors in
certain models for ages were simply Motorola darlington power devices in TO-3
with an HH house mark.

Totally agreed, and from 'binning' experiences I know those numbers can be
VERY tight too. Yield drops off dramatically at the higher end (NOT my
design I'll add).

Off the top of my head approx = to BDX 33/34C IIRC.

Could even be current gain, the Japs do that (GReen ORange BLue etc.. OR
selected higher device voltage in which case you need BDX33/34D (like gold
dust).
