g FERRANTI BCX17 semiconductors|, BCX18 PNP Silicon Planar Medium Power Transistors DESCRIPTION These devices are intended for saturated switching, general purpose switching and driver applications. Complementary to the BCX19 and BCX20. Encapsulated in the popular SOT-23 package these devices are designed specifically for use in thin and thick film hybrid circuits in both industrial and commercial applications. SOT-23 The Ferranti SOT-23 package is formed by transfer moulding a Actual size in inset SILICONE plastic specially selected to provide a rugged one piece encapsulation resistant to severe environments.
