BC490AG Overview

DC current gain' is equal to the ratio of the collector current to the base current, something like Ic/Ib, and this device has 100 @ 100mA 2V DC current gain.A collector emitter saturation voltage of -500mV ensures maximum design flexibility.A VCE saturation indicates a maximum value of Ic (saturation), and a maximum value of VCE saturation (Max).The base voltage of the emitter can be kept at 4V to achieve high efficiency.In definition, current rating refers to the maximum current a fuse can carry for an indefinite period without deteriorating too much, and the current rating of this device is -1A.There is a transition frequency of 150MHz in the part.In extreme cases, the collector current can be as low as 1A volts.
