This is a 1200V / 10A / PIM IGBT module.

I came across this module and had no idea what it was. I have about 30-40 boards with these on them and I don't know how to get them off because it looks like the through hole pins connect directly into other components like capacitors or relays and such (sorry no pics ATM, I'll get some later). I didn't take this off the board, I got the part afterwards and it had a broken plate that covers the internals.

What you don't see is that there is a layer of some kind of clear tacky/slimy silicone like substance, it's like the stuff those toys are made of that stick on the wall and pick up all kinds of dirt, then you wash them off and they look new.

The bottom of the unit is just a solid piece of metal heat sink the whole thing weighs about 8-10oz.






I've also attached the PDF for the unit. I'm trying to figure out what I can do with these as they seem worth saving and they seem to be in good shape.

I'm wondering what the wire leads are made of, if they are all silver possibly? or if there are any recoverable metals (mainly PGM's possibly in there). I don't want to recover them unless these don't work, they are more valuable as working units I would think.

 

Oh home sweet home. I was using such 1200V 500A modules, and need to be honest, most of them I blowed up, until shifted toward another more modern modules. Its rather high cost joy. Sorry, but 10A exibits a bit smalish taste.

the leads look like aluminum.

Well they were free to me. I was just amazed when I saw inside it. I never imagined what they would look like. I'd love to see what a 500A version looks like. Do you have a model number or something close that I can look at?

I'm trying to figure out what to do with all of these that I have. I do need to make some motor speed controls, so maybe these can be used?

 

They are used in motor controls, welders , robots, and inverters anywhere you need a high powered electronic switch. I have a bunch of them too. Most of them are in a push-pull or totem pole configuration, they can source and sink current depending on which side is turned on. The mounting base is insulated from the internals, so some heat sink paste and bolt to a heat sink and your done.

 

These modules are very typical for 3ph inverters - it has a three phase rectifier, three phase bridge and a switch for a brake resistor.
The whole package seems to be soldered using through hole pins into a pcb, so you would have to desolder that to use them for something else. Or just use whatever is on the board to your purposes, that should be fine and probably better than what you will come up with.

Thanks for the reply. I found this piece in the bottom of a tub of boards and then found some intact boards with the piece still on-board. I don't know how to test these to see if they still work and I checked on ebay and the boards are pretty pricey so it might be worth trying to see if I can salvage these especially since I have some uses for them. I have a bunch of 2HP 3ph motors that I'd like to use, but no 3ph power, so it seems that you are saying that these are used to run a 3ph motor from single phase?







This is a separate board by the same manufacturer and IDK if it is used as the controller of the above board or what, but it has the same pin connection (ribbon wire I think??) which is underlined in red in the first picture of each board.



Well I think I'll be glad I saved these from being put through the shredder, it is truly amazing how many perfectly good boards/electronics get scrapped like this b/c the people taking things apart have no idea what they are looking at or maybe they are a little dirty (these had wood dust on them... but they cleaned up really nice!).
