SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

i usually put a small flat head screwdriver at the bottom corner by the pins and pry up on the plastic that works all the time

I was thinking about this concept recently, it would be excellent to be able to refurbish these STK and SVI IC packages!!!

Can you tell me how you opened the modules? Did you use heat to melt the glue? I have had no success trying so far, but I did get one open by cutting into it with a dremel, but that was a bit messy... :P

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

i will make other test with somes mosfet ans i will drop down voltage to make it more compatible with my parts maybe this power module will revive some day

sorry for my poor english im french from quebec

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

long time not posted on this topic just to remind i have this amplifier again and again in standby mode , my transistor was a setup of darlington welcome smoke please dont delete this topic i will rework this subject soon '' C'est mon défi ''

[Jeff Pepin]

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

i have these again yes

[Jeff Pepin]

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

i have 2 of them , with an atmega168 tester sold on ebay the 2 that was not blown resulted that

firt one
second :

both 2 others was blown and not able to test them


i have put this project in standby because im temporary overdosed by theses SVi'S history

ME . SVI
i really sure that on a good road , the P-jfet is probably the P-MOS , and other is probably the N-MOS , i really hate retarded unidentified electronic parts

to be continued , For sure

Do you still have those silicons that you removed?

[Jeff Pepin]

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

after somes research i can'T finally determine if it can be the case of mosfet or igbt but it look definitively one of them ,, need motivation to takeover this project ,,

did i can only replace the 60 V rail by 12V rail low amp , just to test it without blowing anything ? , i fear this mini mig solder

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

and badcaps.net is the best of internet , i really enjoy this experience since a week soon

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

If it is they would have put the word MOSFET on the module to advertise it.

maybe its when the time of '' sold svi'S is more benefit than only mosfet '' begined
maybe they just ordered to manufacturer mosfetS Without encapsulation for they own desing ,

if its mosfets im happy because i have a lot of Broken CAr amps to salvage

i need to test the bc module for proper operation Without Power rail and power devices on it , just to see if base of each channels are good ,

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

here we go !! , so svi's are mosfet based ??

need to sleep

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

I HAVE JUST FOUD!!!

Theses stranges Transistors on Svi's look like

Nmos transistor
Pmos transistor

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

It is not a complete lost due to the fact that you learn quite a bit about the circuits.

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

finally at end this tread will be converting a new class A onto Class B amplifier XD

[Jeff Pepin]

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

yeah for sure , and at this point , i will isolate the 60V rail and see for damage on ic ,, then if it destroyed , i will probably drop the part 2 , eliminatig the whole IC , and build a basic bias network ,

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

More likely you have more damaged parts in that module when the power transistors went out the first time.

[Jeff Pepin]

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

First REsult : Channel 2 Shorted out Collecter/Emmiter on both devices , channel one look good

no smoke

115V bulb trick ready
1,5 Amp fuse rather 5A

Myself AMPlifier

Re: SVI3206D Hybrid IC ( BC POWER MODULE BY SANYO)

The transistors base drive circuits may be damaged when the power transistors went out, they are direct couple circuits. You should plug the unit into the AC socket that will put the 120V lamp in series with the unit you are working on. you can use 60~75W lamp, the lamp will stay on bright if the circuit draws too much current constantly, it saves me many output transistors.

i agree for the lamp in serie really nice idea thanks a lot!
