Need RJK5010/B1DEHQ000014 info/datasheet

[Behemot]

Found this N-FET (and a bridge rectifier) blasted in old Panasonic TV but I am unable to find datasheet or at least good enough info to guess what transistor can I stick in. It is in boost active PFC switching FET.


This website http://www.cybor-tech.com.pl/i89988-...-renesas-.html says it is 500V 40A, that's some crazy shit Isn't it more like 10A, 40 peak? Here http://www.mixelec.fr/article-86439-...n-rjk5010.html they say it's 20A, that's more plausible…

Closest which may suit I have is 2SK2698…who knows how the PFC works here but the total power draw of this thing is 235 W and it has completely separated stand-by PSU (with independent rectifier, cap etc.) so I don't think there will ever be more than 15 A at 325 V in there?

Can't see any in there.

I've soldered in the rectifier (got somewhat short legs so it's more soldered from the upper side but I think it will be OK), transistor and fuses, lighbulb indicated normal operation. After connecting to power grid I got some picture, probably window warning about lack of input (got the display on table so I cannot see much). Will clean the whole interior and do some testing tomorrow but it seems good.

The 2SK2698 is somewhat hot, 70 °C on the tab right after shutdown…but it should be operating up to 150 °C (even though the drain-source resistance rises significantly with temeprature) so I guess it's OK? Other than that I only got some SPP20N60C3 (TO-220F) or 18N50 N-FETs which should have lower losses but smaller package so worse heat transfer. There is probably not anything more powerfull in shops here and if so, incredibly expensive…

150c is the maximum Channel temperature (not the case temperature) which is typical for semiconductor.

It was hot like hell on the other hand it was leant on shelf with paper boxes so I expect slightly better cooling while on the stand. I'll give it back to the owner and if it dies again in future, we have a deal I will remove the PFC completely…without it it will consume like <150 W so it's nothing terrible harmonics-wise.

put a cpu-fan in the case if it's used in a bad location.

Good idea but I've already closed it and there is like 40 screws I think it will be quite better on the stand, I had it standing on shorter side, perpendicularly to internal heatsinks. Normally the air can flow through, like it did in customers living room, there were tons of dust, I've also cleaned that all.
