Abstract: A thermoplastic composition includes: 40 to 75 wt % of a poly(carbonate-siloxane-arylate); 5 to 45 wt % of a poly(carbonate-siloxane) present in an amount effective to provide 0.75 to 7 wt % of siloxane units; 10 to 40 wt % of a polycarbonate homopolymer; 5 to 15 wt % of an organophosphorus compound in an amount effective to provide 0.1 to 1 wt % of phosphorus; and optionally, 0.1 to 10 wt % of an additive composition. The thermoplastic composition has a melt volume flow rate of greater than 6 cm3/10 min. An article molded from the thermoplastic composition has a 2-minute integrated heat release rate of less than or equal to 65 kW-min/m2 and a peak heat release rate of less than 65 kW/m2 and a notched Izod impact resistance of greater than 30 kJ/m2 or greater than 700 J/m2.
