Claim:
1. A polycarbonate composition comprising: (a) from 20 to 80 weight percent of a first polycarbonate component; (b) from greater than 0 to 25 weight percent of a polysiloxane-polycarbonate block copolymer comprising a polycarbonate block derived from bisphenol A and a diorganopolysiloxane block of the general formula (I): (c) from greater than 0 to 5 weight percent of an impact modifier; (d) from greater than 0 to 5 weight percent of an anti-dripping agent; (e) from greater than 0 to 25 weight percent of a flame retardant; (f) from greater than 0 to 30 weight percent of a high heat polycarbonate component comprising 2-Phenyl-3,3-bis(4-hydroxyphenyl)phthalimidine (PPPBP); and (g) balance of one or more additional polymer composition additives; wherein the polycarbonate composition exhibits a notched Izod impact strength greater than 400 J/m as measured according to American Society for Testing and Materials (ASTM) D256 as measured on a bar having a thickness of about 3.2 mm and wherein the composition exhibits a UL-94 flammability rating of V0 as measured on a flame bar having a thickness of about 0.60 mm.
