BC556BU Overview

As the DC current gain is the ratio of the collector current to the base current, for this device the DC current gain is 110 @ 2mA 5V.As it features a collector emitter saturation voltage of -250mV, it allows for maximum design flexibility.When VCE saturation is 650mV @ 5mA, 100mA, transistor means Ic has reached transistors maximum value (saturated).An emitter's base voltage can be kept at -5V to gain high efficiency.In definition, current rating refers to the maximum current a fuse can carry for an indefinite period without deteriorating too much, and the current rating of this device is -100mA.A maximum collector current of 100mA volts can be achieved.
