BD440G Overview

This device has a DC current gain of 40 @ 500mA 1V, which is the ratio between the base current and the collector current.This system offers maximum design flexibility due to a collector emitter saturation voltage of 800mV.A VCE saturation (Max) of 800mV @ 300mA, 3A 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 5V.As defined by current rating, the maximum current a fuse can carry without deteriorating too much is -4A for this device.In the part, the transition frequency is 3MHz.When collector current reaches its maximum, it can reach 4A volts.
