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.
