BFX34 Overview
This device has a DC current gain of 40 @ 2A 2V, which is the ratio between the base current and the collector current.This design offers maximum flexibility with a collector emitter saturation voltage of 1V.A VCE saturation (Max) of 1V @ 500mA, 5A means Ic has reached its maximum value(saturated).A high level of efficiency can be achieved if the base voltage of the emitter remains at 6V.This device has a current rating of 5A which corresponds to the maximum current it can carry for an indefinite period without deteriorating too much.As you can see, the part has a transition frequency of 100MHz.A maximum collector current of 5A volts is possible.
BFX34 Features
the DC current gain for this device is 40 @ 2A 2V
