FJT44KTF Overview
As the DC current gain is the ratio of the collector current to the base current, for this device the DC current gain is 50 @ 10mA 10V.Single BJT transistor has a collector emSingle BJT transistorter saturation voltage of 750mV, which allows maximum flexibilSingle BJT transistory in design.As a result of vce saturation, Ic reaches its maximum value (saturated), and vce saturation(Max) is 750mV @ 5mA, 50mA.Single BJT transistor is possible to achieve a high level of efficiency by maintaining the emSingle BJT transistorter base voltage at 6V.Its current rating is 300mA, which means that it can sustain a maximum current for an indefinite period of time without degrading too much.Single BJT transistor can take a breakdown input voltage of 400V volts.During maximum operation, collector current can be as low as 300mA volts.
