BD249B-S 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 10 @ 15A 4V.As a result of vce saturation, Ic reaches its maximum value (saturated), and vce saturation(Max) is 4V @ 5A, 25A.Single BJT transistor is possible to achieve a high level of efficiency by maintaining the emSingle BJT transistorter base voltage at 5V.During maximum operation, collector current can be as low as 25A volts.
BD249B-S Features
the DC current gain for this device is 10 @ 15A 4V
the vce saturation(Max) is 4V @ 5A, 25A
the emitter base voltage is kept at 5V
