BC557B Overview
As dc = Ic/Ib, DC current gain is the ratio of base current to collector current, and DC current gain for this device is 180 @ 2mA 5V.When VCE saturation is 650mV @ 5mA, 100mA, transistor means Ic has reached transistors maximum value (saturated).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 -100mA.In the part, the transition frequency is 150MHz.
BC557B Features
the DC current gain for this device is 180 @ 2mA 5V
