SILICON POWER TRANSISTOR
2SA1744
PNP SILICON EPITAXIAL TRANSISTOR
FOR HIGH-SPEED SWITCHING
The 2SA1744 is a power transistor developed for high-speed
switching and features a high h
FE
at Low V
CE(sat)
. This transistor is
ideal for use as a driver in DC/DC converters and actuators.
In addition, a small resin-molded insulation type package
contributes to high-density mounting and reduction of mounting
cost.
