BC557B Overview
In this device, the DC current gain is 180 @ 2mA 5V, which is the ratio between the base current and the collector current.When VCE saturation is 650mV @ 5mA, 100mA, transistor means Ic has reached transistors maximum value (saturated).As defined by current rating, the maximum current a fuse can carry without deteriorating too much is -100mA for this device.As a result, the part has a transition frequency of 150MHz.
BC557B Features
the DC current gain for this device is 180 @ 2mA 5V
the vce saturation(Max) is 650mV @ 5mA, 100mA
the current rating of this device is -100mA
a transition frequency of 150MHz
