RJH3047 (IGBT) datasheet wanted

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...).

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.
 
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. :(

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
