SILICON POWER TRANSISTOR
2SA1646, 2SA1646-Z
PNP SILICON EPITAXIAL TRANSISTOR
FOR HIGH-SPEED SWITCHING
The 2SA1646 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
power supplies, DC/DC converters, motor drivers, solenoid drivers,
and other low-voltage power supply devices, as well as for high-
current switching.
