BD249-S 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 10 @ 15A 4V DC current gain.Saturation of VCE means Ic is at 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.Collector current can be as low as 25A volts at its maximum.

BD249-S Features
