What's this please? (Component Advice)

[TerraHertz]

Ow! That's not good at all. Custom analog, proprietary, and probably no public data at all. Darn it.
That leaves just observing what it does, then looking for a way to replace it with something easily available.
Where 'it' would probably be easiest if I ignore the IC, and consider that whole rider board as a black box.

Thanks though.

I've been checking too on the controller for the oven, no luck this time.

[ddavidebor]

I've got a component that I would like to figure out what it is  =0).

Little rectangle notched on one side.   tapered back top.   and stamped with FIOY  (not sure if F10Y or FIOY) on it.

check with multimeter if it is a diode.

Please, remind me the name of this npn/pnp voltage amplifier configuration.

Please, remind me the me of this npn/pnp voltage amplifier configuration.

Is it just a non-inverting amplifier of some form?

Looking for any info for smd  component marked "K4A". It is most probably some kind of switching regulator IC.
Two of those are in power supply part of "AR.Drone" quadcopter that I'm trying to repair.


(image taken from some Russian forum)

It's an AZ431 made by BCD Semiconductor.  Shunt mode regulator.

[dr_p]

package seems to be DFN-8, so the 431 varity doesn't fit, plus the OP mentioned something about being directly connected to an inductor.

Here's an IC that is some kind of switch-mode controller. It's on an inverter-type microwave oven PCB which I'm interested in adapting as a HV power supply. Depending on whether the circuit is suitable.
So far, no luck searching for the part number: AN9DB07SB 929S6E02

The oven is a Panasonic NN-SD686S, but I've seen this identical inverter PCB used in two other different Panasonic microwave ovens, so I'm hoping it's going to be common 'street findings' in future.

Full story with teardown pics here: http://everist.org/tales/20130308_microwave_hacks.htm

No help on the IC, but I have some answers to other questions you posed at the linked site.
Some Litz wire is available here:

And in the transformer, the extra magnetic path (the one with the wide gap) introduces a controlled amount of leakage inductance by creating flux that does not couple to the secondary.  It saves having an extra inductor component in series with the primary winding since it is incorporated into the transformer.  It's probably a resonant converter.

Probably too late to help you, but it looks like an ICPF10 400mA semiconductor fuse.

IMHO looks like a Sziklai pair. Sometimes also called a complementary darlington - because it uses one PNP and one NPN. You can read up here:

[Hardcorefs]

Looking for any help on the following parts:

2160 7A1
16UN1801 0612 G

They are part of a buck voltage converter around a MAX8538

Thanks

[Hardcorefs]

OK
 I found the  16UN part, seems philips make TWO parts with exactly the SAME part number

One is SOT23 which is only a single part, and it was this showing up in searches......

So I just need to know the other part.

[c4757p]

The other one is a MOSFET.

[Hardcorefs]

Yep... that I know , I was looking for a part or manufacturer ref....

[Hardcorefs]

K got it!!!!

Look what I found in a dumpster-dive.  A set of 5 serious diodes D2-25-4 and D2-25-7. Any idea how much current and voltage it can rectifier? These things are biggest semiconductors I ever hold in my hand with M-12 bolt to connect to the heatsink.

[SeanB]

Well, they are Russian made, so probably 25A units that can be used as room heaters.......

[ResR]

Perfect.  It is sub-zero cold here for many months from October to March/April  Hmm... On one russian site was written that it's 250A 400V (?) although someone from my work said too that it maybe is just 25A diodes._

[G7PSK]

I had a mig welder that had three similar looking diodes but UK made that was rated to 200 amps the transformer was three phase.

[PA0PBZ]

Looks like 25A, 400 and 700 volts, see:

http://www.ebay.com/itm/D2-25-6-NEW-INDUSTRIAL-RECTIFIER-DIODE-25A-600V-/250684091515

[ResR]

eBay?    I don't trust that site for accuracy. I'm planning to make a decent PSU from parts i have in a basement or in my mind, my cardboard box transformer PSU burned out the compact bridge rectifier again dispite the forced cooling of the fan while testing a small schematic, 25A should be fair enough, but 250A is better chances to survive accidental shortcuts. Although it is similar or same as the one in that link._

Any info on a TO-3 package labeled:

    M
10243
 8439

? The M looks like the Motorola logo, and the device is on a 48V 3A PS. Thanks for the help.

Probably a house labeled pass transistor. But Lambda also used dual rectifiers in a TO-3, so you should find a schematic or draw out the circuit. If it's a pass transistor, it's probably non-critical, just make sure the V/A ratings are big enough. I used some 2N6284s to fix a Lambda 24V/3A linear.

[kizzap]

I don't really need any help with identification...more...just thought it was a funny brand...

[orbiter]

I've not seen that make before either, just another Taiwan band I guess. I'd rather them be called Su'spect, though, because at least then I'd know what I was dealing with

I'm assuming you already know the two in the centre of shot are failing (tops bulged)
