SILICON POWER TRANSISTOR
2SA1648,1648-Z
PNP SILICON EPITAXIAL TRANSISTOR
FOR HIGH-SPEED SWITCHING
DATA SHEET
c
2002
The mark shows major revised points.
The 2SA1648 is a mold power transistor developed for high-
speed switching and features a very low collector-to-emitter
saturation voltage.
This transistor is ideal for use in switching regulators, DC/DC
converters, motor drivers, solenoid drivers, and other low-voltage
power supply devices, as well as for high-current switching.
FEATURES
Available for high-current control in small dimension
Z type is a lead processed product and is deal for mounting a
hybrid IC.
Mold package that does not require an insulating board or
insulation bushing
