RJH3047 (IGBT) datasheet wanted

[Pafi]

And RJP3043 too. These are 300 V IGBT-s, I'd like to use them in ClassD amp, but I don't know even the manufacturer of them.

I measured already most of DC parameters, but detailed switching parameters are needed (Eoff, Qrr of diode, stb...).

I'm searching info about 2 other IGBT also. They are IXYS made, but I don't find them on the official homepage. IXGP70N33TBM-A

 

[Pafi]

And IXGQ90N33TCD1

Where did you get these IGBTs? Are they semi-custom parts being used by some amplifier manufacturers in agereement with semiconductor brands before they are released to the general public?

 

[Pafi]

I dismounted them from some rejected PCB from Samsung. It wasn't an amplifier, nor an SMPS, I guess it was a driver of some kind of big display, or vehicle. They seem to be new development indeed, but unfortunately not especially for audio.

Hi Pafi!
I found similar one : IXGQ90N27PB
http://ixdev.ixys.com/DataSheet/DS99609B(IXGQ90N27PB).pdf
IXGP and IXGA parameters is equal. (the difference is the package)
IXYS don't like to notify Qrr in body diode.
Probe it, be brave...
Regards!

Hi!

Thanks! Sadly this has too high fall time for audio.

I've tried some of them (RJ...), and they weren't good enough (eg. too high switching loss -> damaged at about 25...30 A peak current), but I think if I saw the datasheet, maybe I could figure out what to modify to reach a little higher efficiency.

I saw so many potencial in RJP3043! Vcebr=360V, Vce=1.5V @ 16A, tdon=20 ns, tdoff=60 ns, Qg=~30 nC... but current "tail" seems to be too long.

I've tried some of them (RJ...), and they weren't good enough (eg. too high switching loss -> damaged at about 25...30 A peak current)

what kind of the swicthing freq. ?
The RJ...s may be good for classD subwoofer amp with lower Fsw. (around 100-150kHz)
Did you probe IXGP70N33 ? looks more useful the TO220 package IGBT.

 

[Pafi]

Unfortunately the switching freq was not fixed, so I can tell only the idle freq: 200 kHz, but this is somewhat irrelevant.

I didn't try IXGP70N33, mainly because the isolated package can dissipate very little power. I'm planning to remove isolation from the bottom... This has an ultra low saturation voltage (1V @ 16A), so I'm going to use in (resonant) power supply instead of in amp. I don't think it would be fast enough.

RJ...s are usable in sub amp, but worse than the previously used HGTG12N60A4D.

hello i need gp70n33 please could you help me

 

[Pafi]

OK! Give me your address! How many do you need?

RJH3047 datasheet

Hello,

I'm searching for that device to repair my samsung television.

Can you send me a RJH3047? ( i will pay for is)

I have already discovered the exact part name is
RJH3047DPK

VCES= 330V
IC = 50A
IC peak = 250A
tf= 0.15
trr = 0.06 µs
VCE(sat) = 1.5V

it is from renesas

greetings

those parts are used in plasma display panel sustain modules guys.

Just so your aware.

(old thread I know, but i figured i would post it)
