2SB1257 Overview

DC current gain' is equal to the ratio of the collector current to the base current, something like Ic/Ib, and this device has 2000 @ 3A 4V DC current gain.A VCE saturation (Max) of 1.5V @ 6mA, 3A means Ic has reached its maximum value(saturated).The part has a transition frequency of 200MHz.Maximum collector currents can be below 4A volts.
