2SA1909 Overview

In this device, the DC current gain is 50 @ 3A 4V, which is the ratio between the base current and the collector current.Single BJT transistor means that Ic is at Single BJT transistors maximum value (saturated), so the vce saturation(Max) is equal to 500mV @ 500mA, 5A.As you can see, the part has a transition frequency of 20MHz.During maximum operation, collector current can be as low as 10A volts.
