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 :

30$ zero in stock
They are in end of life warning
You have this one, 36 parts left, and the price is +/- 60$

If you search this : NPN DARLINGTON POWER MODULE
Google fuu wil show you some results, you have some modules on ebay ... its the datasheet who's hard to get ?
