panasonic tnpa5330 transistors

[dj01fad]

I have this board (tnpa5330) from a p42gt30 and it's broken. it has the usual 30f131x3 and rjp30x3 blown. now... I am out of stock on rjp30, and have only 2 or 3 original 30f131, and I am wondering if I can use some DG301 or DG302 instead of them? Did someone else tried this? I know they are used (DG301) on tnpa5351 board, in 46g30 and 50g30 TV.

Hope fully your 30F131 are good and not the bad chinese ones but the DG301 appears to be 330V 40A 250a pulse max, The RJP30H2 is 360V 35A.
30F131 360V 30A, 200A pulsed.

I'd give them a go.

At the moment I'm using IRG7S313U which are obsolete but also 330v 40A on a 5349 in place of the 30F131 and they appear ok

Re: panasonic tnpa5330 transistors

Then I'll give them a go, and I hope the'll do the job. my 30f131 are all originals, also dg301 and dg302. I know this because I have them from a panasonic service. I'll share a picture when I'll get home.
On the other hand, I found here at a local supplyer fgd4536 - 21 pcs at 1.75 euros/pc...
Thanks.

Re: panasonic tnpa5330 transistors

Bad power supply also?

[dj01fad]

Re: panasonic tnpa5330 transistors

yes, bad power supply also. I found only 2 R6015 blown, and I have to find them too. do you have an ideea on some replacements? I have here some 12N50 if I'm not wrong, but I'm not sure the'll do the job.
Do you think it may be something else blown on the power board? On a first check I found only these two R6015...
Interesting thing with this TV, because I took it with "doing nothing" and no power led, hoping it is the A board (have one spare), and when I received it, it turned out to be a 7 blinker... this is it now...
Anyway, I have to order some transistors, but the delivery time is about 7 days or more...

[dj01fad]

Re: panasonic tnpa5330 transistors

yessss it's a fix! with 12N50 in the supply and dg301 instead of rjp30 on SN board, and it's working perfect! 18 hours until now and it's ok. so my last 3pcs 30f131 were ok...
but now I am afraid to order again, so I think I'll go for the fgd4536 from now on.

[Moreno83]

Re: panasonic tnpa5330 transistors

Aren't they "R6020" on the power supply? Im using those and they work also. Got them from aliexpress/China and they are all ok!

Do you get the DG301 from china also? What about when the tv is on dynamic? ( picture mode ). Do you cool the parts or?

Re: panasonic tnpa5330 transistors

Sorry for thread hijacking, but i have a question.
For example, for the older sets that use TO220 package IGBTs like 30f125, 45g128, rjp63f3 can i buy one sort, in this case RJP63F3 which should cover all the others, lower value ones. Therefore use all the same igbts for Q401, Q421, Q661 etc. It should work?
It's cheaper to buy 50-100 pcs, and the other advantage is that you don't need to think which one to put where?

Please correct me if i am wrong
Which are dissadvantages of this?

I've had this thought plenty of times. I thought q660 in a lot of instances is a FET?

Anyway they're all varying specs and I don't know the smaller detail on the specs but if you've got the TVs and boards to play with experiment and see.

So far I've used a RJP56F4A in place of a 63F3A and that was because Someone had a Board from a 58" V20 I think and Q661 it had that.

hard to find datasheets for all these but there appears to be a convention they use to rate these. The first digits are voltage and the last is current.

63F3 is 630V 40A, a 56F4 I expect is 560V 45A, 43F4 430V 45A, 30E2 is 360V 35A, the E3 40A.

In the Panasonics in the same part of the cct for example 2009-2010 boards a DG502, I've seen 2PG011, RJP56F4A used.

The 2PG011 is 540V, 40A 230A peak pulse and I know the DG502 replaced that . The 2PG009 is 20V less but those 2PG were discontinued as has most of the others too.

I've used 56F4A and 2PG011 on a couple of 5081 boards and also used just 2PG011 for both DG402RP and DG502LW. Both ran ok but neither have been put into constant use yet.

The 56F4a in place of the 63F3 has been fine running in a 5066 for a couple of months now.

Re: panasonic tnpa5330 transistors

Yes, my bad for Q601, it's a fet

I saw that you have used 56f4 in place of 63f3 so i copied you, but later i changed it because i found a 63f3 so didn't want to gamble
So RJP63F4 should be 630V 40(45)A? If so it should substitute all of these before mentioned?
The worst thing is we don't have datasheets so can't be sure for the full specs of devices
Or something like this: for Q401,Q402, Q403, Q421, Q422, Q423, Q441, Q451, Q621 put a DG502 or 56f4a?
It seems to me that i will go with RJP63F4A for all of them, just hopeing i won't get fake ones :rolleye:

[Moreno83]

Re: panasonic tnpa5330 transistors

So you want to use RJP63F4A for all parts? Like 30F131/RJP30H2A/DG302 etc?

If they're cheap enough , why not. As I have 6 of these 5081 boards now the last two I experimented with since I ran out of parts and I had a bunch of 56F4 and a couple of 4782 boards I failed to get 100% so rather than waste all the good parts recycled some of the IGBTs into to 5081. I also used 56F4 in place of DG502 on a 5105 board too.

I blame boredom for this irratic behaviour

The logic I used for using the 56F4A in place of the 63F3 was I expect it has higher current rating, there would not be voltages there that require a 630V transistor and If a 58" SC from the same generation using the same Vsus levels and a higher current draw can run with it then the smaller models can too. That's how I see it. A 5175 is like a 5081 on steroids, bigger and some extra iGBTs in parrallel,

Re: panasonic tnpa5330 transistors

Yes, that's the idea, manufacturers are allways looking to cut down the production cost, so every cent matters to them, i don't have that problems, dollar more or less, same thing
If we have one that can cover them all, why not to do it that way
It's the highest spec one, voltage and current wise, peak current they are all the same

[tw2005]

Re: panasonic tnpa5330 transistors

Another worth mentioning is RJP6065 similar to the RJP63

Re: panasonic tnpa5330 transistors

Except collector peak current which is 100A according to the datasheet, and 200A for RJP63F3 (4) sounds way better

Sure, but you have to wonder what these devices really see in operation and it's doing the same job in a 4782. Just saying if you have boards laying around there's bits to be used.

Re: panasonic tnpa5330 transistors

I am sure Tom knows the answer

Well i decided to try it, and will give the update once when i install them

Re: panasonic tnpa5330 transistors

These are really tricky boards to repair. I'm rebuilding these boards at the moment. I got like 5/6 of these boards that were worked on by other people. ( Thats why they are so difficult :p )

Removed all bad parts and checked the buffers. Buffers are ok so i started to rebuild the board. ( IGBT's/Diodes + the two small ic's. ).
I still get 7 blinks and no shorted parts. I think one or more ic's in the sos circuit are bad.


Boards that are not worked on by others are "easy" to repair.

Re: panasonic tnpa5330 transistors

Hi,anyone could help me to fix my tnpa5330 board .I have removed all the shorted Fets .
I have shorted diode near the Buffer IC. See photo
Is this would be normal ? I have measured out the board and are all Ok .
