The 2SA1647 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.
• 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
