Can anyone help me find replacement for old ESM2893V transistor. It was used in Froniu Transarc 500 (Castolin Transmodul 500) welder. It look like this:


Maybe someone have service manual for this welder?

They where used in arc welders   =   NPN power darlington   28v at 93 amps

I think sgs thomson have equivalents ??

They were similar to ESM2030DV on another thread,  some one had 14 of them to sale in 2008 ?  or an esm 3045dv  as a substitute ???

Only links ive found : http://www.sabaelec.ir/products_new.asp?groups=315&gname=ISOTOP%20Transistors&mname1=Transistors
