BD239A-S Overview

In this device, the DC current gain is 15 @ 1A 4V, which is the ratio between the base current and the collector current.When VCE saturation is 700mV @ 200mA, 1A, transistor means Ic has reached transistors maximum value (saturated).An emitter's base voltage can be kept at 5V to gain high efficiency.Single BJT transistor is possible for the collector current to fall as low as 2A volts at Single BJT transistors maximum.
