BC557BTA Overview

DC current gain in this device equals 200 @ 2mA 5V, which is the ratio of the base current to the collector current.The collector emitter saturation voltage is -250mV, giving you a wide variety of design options.Saturation of VCE means Ic is at its maximum value (saturated), and VCE saturation (Max) is 650mV @ 5mA, 100mA.The base voltage of the emitter can be kept at -5V to achieve high efficiency.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.A transition frequency of 150MHz is present in the part.Input voltage breakdown is available at 45V volts.Single BJT transistor is possible for the collector current to fall as low as 100mA volts at Single BJT transistors maximum.
