BC449A 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 120 @ 2mA 5V DC current gain.As it features a collector emitter saturation voltage of 125mV, it allows for maximum design flexibility.VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.Keeping the emitter base voltage at 5V can result in a high level of efficiency.According to definition, current rating describes the maximum current a fuse can carry indefinitely without deteriorating too much, and this device has no current rating.There is a transition frequency of 200MHz in the part.When collector current reaches its maximum, it can reach 300mA volts.
BC449A Features
the DC current gain for this device is 120 @ 2mA 5V
