BC557ATA Overview

This device has a DC current gain of 110 @ 2mA 5V, which is the ratio between the base current and the collector current.A collector emitter saturation voltage of -250mV ensures maximum design flexibility.A VCE saturation indicates a maximum value of Ic (saturation), and a maximum value of VCE saturation (Max).A high level of efficiency can be achieved if the base voltage of the emitter remains at -5V.The current rating of this fuse is -100mA, which means that transistor can carry an indefintransistore amount of current wtransistorhout deteriorating too much.As a result, the part has a transition frequency of 150MHz.As a result, it can handle voltages as low as 45V volts.During maximum operation, collector current can be as low as 100mA volts.
