Dear Sirs! I want to repair electronic ballasts. In the same type of ballast (TRILUX) i found a lot of different Mosfets, most from Int.Rectifier: IR822G,824G,826G/C, 831C, 851C, 852 F, 907C, 910C 912C, IRFBE30, IRF 820, IRF 830. Only the three last ones are listed and available. I cannot find datas from the other types. Is it an agreement between the manufactures? Is it possible to replace them with one cheap replacement transistor? In average i have to replace 2 transistors and a safety resistor for every ballast. At a price of 3 to 5 Euro (1 Euro= 1.19 US$) for one transistor it does not pay to repair the devices with defective Mosfets. Excuse my bad English!
Thank You!
Best regards,
Friedrich.
