DESCRIPTION:
The CENTRAL SEMICONDUCTOR CTLT3410-M621
and CTLT7410-M621 are Low VCE(SAT) transistors in
a very small leadless 1x2mm surface mount package,
designed for applications where small size, operational
efficiency, and low energy consumption are prime
requirements. Due to the leadless package design,
these devices are capable of dissipating up to 3 times
the power of similar devices in comparable sized
surface mount packages.
