BD159 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 30 @ 50mA 10V.The base voltage of the emitter can be kept at 5V to achieve high efficiency.Fuse current ratings refer to how much current the fuse can carry for an indefinite period without deteriorating too much, and this device has a current rating of 500mA.Collector current can be as low as 500mA volts at its maximum.
