I think the -70 indicates voltage or current.Does anyone have a spec sheet on this part? It is used in a JVCHXZ30. I
would like to use it in a different project but the data sheet is not to be
found. Numbers all around STK432-70 come up but not that part.
Total output power, isn't it ? 2 x 35w RMS ? Any version of the STK432 dataOn Sun, 28 Mar 2010 11:36:02 -0500, "Herman"

Total output power, isn't it ? 2 x 35w RMS ? Any version of the STK432 data
sheet should be good for the basic pinning and specs. Looks like there are
50 watt, 70 watt and 90 watt versions of it. I guess that if you have one
with no dash number, it's probably a version that's less than 50 watts total
output. If you have a JVC model that it's already used in, then just look up
the specs for that model. That should give you a good indication of its
power capability, and a quick squint at the schematic will tell you all you
need to know about operating voltages, pinning, and support circuitry.

Download HX-Z30 service manual for free:What I need is pin outs, voltage limits, temperature characteristics.
Anyone that indicates they have a .pdf spec sheet gives me a "not found" or
a spec sheet on some other device such as a voltage regulator.

Agreed. If the OP can't find a genuine data sheet, that might suggest that
it's now an obsolescent device anyway. Obtaining the service manual for
the JVC hifi that it's in, will tell all. Well, certainly pinouts, and the
voltages that JVC are applying to it in that hifi can be taken as being
the limits for reliable operation. In my experience, most hifi
manufacturers don't 'reinvent the wheel' with their products. They pretty
much graft ICs and t.f. hybrid modules like STK's into their designs,
using an exact copy of the manufacturer's 'typical application' schematic,
right down to the values and recommended types for support components.
Obviously, the JVC manual is not going to tell you anything about the
temperature characteristics of the device, but are these actually
important to the OP's application anyway (which is presumably a personal
one-off ?) As long as the device is adequately cooled, exact thermal specs
should not be an issue. Manufacturers of hifi equipment don't waste money
in their designs, so you can bet that the heatsinking that JVC are
applying, is the minimum you can get away with for full rated output
power, in line with the level of supply rails they are using.

Sounds like aircraft stuff huh?I appreciate all the suggestions. I had already used the schematic to decide
what I needed to do.
I am making a 3 phase 400 cycle 130 volt power supply for some test
equipment. I am driving a 18 volt power transformer in reverse (18 volts
in, 125 volts out)and wanted to make sure I did not over stress anything.
I picked this part since I had some in stock and it was only $3.18. I
thought it would be easy to find the specs.
Yes, I make some test equipment for military aircraft. They need a testerOn Tue, 30 Mar 2010 06:35:38 -0500, "Herman"
