DESCRIPTION:
The Central Semiconductor CMKT3904 (two single
NPN), CMKT3906 (two single PNP), and CMKT3946
(one each NPN and PNP complementary) are
combinations of transistors in a space saving
SOT-363 ULTRAmini™ package, designed for
small signal general purpose amplifier and switching
applications.
