BC557BU 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.Saturation of VCE means Ic is at its maximum value (saturated), and VCE saturation (Max) is 650mV @ 5mA, 100mA.The emitter base voltage can be kept at -5V for 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.The maximum collector current is 100mA volts.
