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.
FEATURES
Mold package that does not require an insulating board or
insulation bushing
Fast switching speed
Low collector-to-emitter saturation voltage:
