STN749 Overview

As the DC current gain is the ratio of the collector current to the base current, for this device the DC current gain is 100 @ 1A 2V.Saturation of VCE means Ic is at its maximum value (saturated), and VCE saturation (Max) is 600mV @ 300mA, 3A.A high level of efficiency can be achieved if the base voltage of the emitter remains at 5V.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 -3A.An input voltage of 25V volts is the breakdown voltage.A maximum collector current of 3A volts can be achieved.
