DESCRIPTION:
The CENTRAL SEMICONDUCTOR CMBT3904E
(NPN) and CMBT3906E (PNP) are general purpose
transistors with enhanced specifications. These
devices are ideal for applications where ultra small
size and power dissipation are the prime requirements.
Packaged in the FEMTOmini™ SOT-923 package,
these transistors provide performance characteristics
suitable for the most demanding size constrained
applications.
