BUL128D-B Overview
This device has a DC current gain of 12 @ 2A 5V, which is the ratio between the base current and the collector current.This design offers maximum flexibility with a collector emitter saturation voltage of 500mV.A VCE saturation (Max) of 500mV @ 1A, 4A means Ic has reached its maximum value(saturated).A high level of efficiency can be achieved if the base voltage of the emitter remains at 9V.A maximum collector current of 4A volts is possible.
BUL128D-B Features
the DC current gain for this device is 12 @ 2A 5V
a collector emitter saturation voltage of 500mV
the vce saturation(Max) is 500mV @ 1A, 4A
the emitter base voltage is kept at 9V
