The 2SA1647 is a mold power
transistor developed for highspeed 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. Low collector saturation voltage:
VCE(sat) = −0.3 V MAX. (@IC = −3 A) Fast switching speed:
tf = 0.4 µs MAX. (@IC = −3 A) High DC current gain and excellent linearity
