2SA1644 transistor equivalent, power transistor.
*Developed for use in switching power supplies, DC/DC
converters, motor drivers, solenoid drivers, and other low-vol.
*Collector-Emitter Sustaining Voltage-
: VCEO(SUS)= -100V(Min)
*High DC Current Gain-
: hFE= 100(Min)@ (VCE= -2V , IC= -1A)
*Low Saturation Voltage-
: VCE(sat)= -0.3V(Max)@ (IC= -3A, IB= -0.15A)
*High Speed Switching
*Minimum Lot-.
