MMDT3904
DUAL SURFACE MOUNT NPN TRANSISTORS
This device contains two electrically-isolated 2N3904 NPN transistors. The
two transistors have well matched hFE and are encapsulated in an ultra-
small SOT-363 (SC70-6L) package. This device is ideal for portable
applications where board space is at a premium.
