BC557BTFR 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 200 @ 2mA 5V.A collector emitter saturation voltage of -250mV allows maximum design flexibility.Saturation of VC means the Ic value is at its maximum, so vce saturation (Max) is 650mV @ 5mA, 100mA.Continuous collector voltage should be kept at -100mA for high efficiency.The base voltage of the emitter can be kept at -5V to achieve high 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.The maximum collector current is 100mA volts.
