BD239B-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 15 @ 1A 4V DC current gain.A VCE saturation indicates a maximum value of Ic (saturation), and a maximum value of VCE saturation (Max).Continuous collector voltages of 2A should be maintained to achieve high efficiency.A high level of efficiency can be achieved if the base voltage of the emitter remains at 5V.During maximum operation, collector current can be as low as 2A volts.

BD239B-S Features

the DC current gain for this device is 15 @ 1A 4V
