BC449AG Overview

This device has a DC current gain of 120 @ 2mA 5V, which is the ratio between the collector current and the base current.The collector emitter saturation voltage is 125mV, giving you a wide variety of design options.Single BJT transistor means that Ic is at Single BJT transistors maximum value (saturated), so the vce saturation(Max) is equal to 250mV @ 10mA, 100mA.A high level of efficiency can be achieved if the base voltage of the emitter remains at 5V.Fuse current ratings refer to how much current the fuse can carry for an indefinite period without deteriorating too much, and this device has a current rating of 300mA.As a result, the part has a transition frequency of 200MHz.Collector current can be as low as 300mA volts at its maximum.
