BC557BBU Overview

In this device, the DC current gain is 200 @ 2mA 5V, which is calculated by taking the ratio of the base current to collector current and dividing transistor by two.As it features a collector emitter saturation voltage of -250mV, it allows for maximum design flexibility.A VCE saturation indicates a maximum value of Ic (saturation), and a maximum value of VCE saturation (Max).Single BJT transistor is possible to achieve a high level of efficiency by maintaining the emSingle BJT transistorter base voltage at -5V.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.When collector current reaches its maximum, it can reach 100mA volts.
