Panasonic Microwave Inverter Transistor?

[Wilton Itamoto]

I am currently working on a Panasonic microwave oven model NN-S762WF. I need
the part# for Q702 on the inverter board. The transistor is burnt and I
cannot read the number on the case. Unfortunately I do not have another
inverter board on hand and Panasonic does not provide the schematic.

Anyone replaced one of these or know the part number?

[Wilton Itamoto]

Any Ideas?

I have the part number for the power mossfet. It is 1M30D-060. Now the
question is where do can I get this part? Panasonic does not have a listing
for this part.

This service manual has a circuit diagram that may be similar:
http://www.eletrodomesticosforum.com/downloads/microondas/Panasonic_NN-G62BH.pdf

Q702 is "AESPGT30J322" which is equivalent to a 1M30D-060.

See page 10-6 of this catalogue:
http://www.wagner.net.au/catalogue/10_Microwave.pdf

It talks of a "TWO TRANSISTOR OEM KIT". Trade price for KIT691 is
AU$28.75.

Here is the relevant excerpt from the catalogue:

I'm currently working on a Panasonic NN-C994S Convection Oven, and the converter has a blown mosfet # 1M30D-060. The inverter model is A606Y4T00AP.
Will any 1M30D-060 do the job?

Regards

One that isn't shorted... I don't know if these are counterfeited but if you have a known good supplier where you are, pay a little more and get it from a reliable source - perhaps Panasonic directly if they still provide discrete components for consumer items. You may need a Panasonic part number, not the generic number. Start with acquiring a service manual and go from there. The manual will be helpful if the mosfet took out the gate components.

I downloaded the SM and there is no breakdown on the inverter, just the part number of the inverter board assy is available. My cost is $138 plus shipping U.S. There are seller on ebay selling these mosfets as "pulls", which to be honest I'd rather use than a new one of dubious provenance.

Keep in mind you have no way to know an "ebay pull" is really a "pull"
from another unit vs. someone simply offering the same "dubious
provenance" part while stating it was a "pull".

I.e., the ebay seller could simply be offering the same dubious part,
with the "value added service" of applying a small bit of solder to the
pins to make it look "used" before shipping it to you.

Since pulls sell for less than "originals", the likelihood of someone misrepresenting a part as new original is much higher than someone misrepresenting a part as used.

Hi folks,
I've received the transistors this morning, however, I am unsure if I will install them. I was supposed to receive a 1M30D-060 but received a suspicious 1MB30D-060. The datasheet from Fuji mention a 1MB30-060 and a 1MBH30D-060 but there's nothing about a 1MB30D-060 which makes me wonder if I've received bootlegs. (Fast forward 2 hours later) I have inspected inspected both transistor more closely and I'll be damned if these thing haven't been sanded down and re-lazer etched. You can clearly see the grain : /

Ordering most any simiconductor off ebay from another country is very
chancy. I know several in the local ham club that bought from over seas
and the simiconductors were faulty in one way or another. I bought some
20 watt RF transistors and they would only make about half the poewr
they should have. Reordered from a reliable source in the US and the
new ones worked like they were supose to.

I may have a suitable sub in my plasma TV parts supply (that I've packed away). If I have anything that will match up, they're yours.

Which case style do you have?

Thanks for the offer. The old 1M30D-060 is a To-3PF, I believe, with the low profile upper half.

[ohg...@gmail.com]

I went through everything I have including scrapped plasma sustain boards, and all the big plastic transistors I have are power mosfets. Sorry. What I would do is use DigiKey or Mouser's search parameter to select a suitable replacement.

There is always this - if you can find a data-sheet.

I just ordered a pulled 1M30D-060 from Dalbani which is based in FL. I've checked around and they appear to be a reliable source that has been around for ages. They're not fake proof but, apparently, when a problem occur, they're quick to dispatch a replacement.

[Three Jeeps]

I can support the fact that Dalbani has been around for a long while and used to order tv, vcr, and microwave parts from them. Am surprised their website is parked. They out of business?

I used to buy parts from Dalbani many years ago, and they were one of the suppliers that sent me counterfeit semis. I mostly bought basic stuff from them like VCR mechanical parts after than, but no more semis. They're still in Florida but I'm sure they're not the same company they were.

[Chuck]

Same here. Their STR regulators were counterfeit plus their
replacement flybacks didn't work.

I installed the new transistor a few months back and the oven function works again, however, the maximum temperature it can reach is 350F. It's all right, I can still cook, it just take a wee bit more time. In my full size oven, it takes 20 minutes to bake croissants at 400F. In the Panasonic NN-C994S, it takes 30 minutes at 350F.
