BF423 Overview
In this device, the DC current gain is 50 @ 25mA 20V, which is calculated by taking the ratio of the base current to collector current and dividing transistor by two.The collector emitter saturation voltage is -500mV, which allows for maximum design flexibility.When VCE saturation is 500mV @ 2mA, 20mA, transistor means Ic has reached transistors maximum value (saturated).With the emitter base voltage set at 5V, an efficient operation can be achieved.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 -50mA.As you can see, the part has a transition frequency of 60MHz.The maximum collector current is 500mA volts.
