BD249A-S Product Details
BD249A-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.Single BJT transistor means that Ic is at Single BJT transistors maximum value (saturated), so the vce saturation(Max) is equal to 4V @ 5A, 25A.Keeping the emitter base voltage at 5V allows for a high level of efficiency.Single BJT transistor is possible to have a collector current as low as 25A volts at Single BJT transistors maximum.
BD249A-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
