BUL742A 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 16 @ 800mA 3V DC current gain.Vce saturation?means Ic is at its maximum value(saturated), and the vce saturation(Max) is 1.5V @ 1A, 3.5A.Single BJT transistor is possible to achieve a high level of efficiency by maintaining the emSingle BJT transistorter base voltage at 12V.Normally, a fuse's current rating refers to how much current it can carry without deteriorating too much, which in this case is 4A.When collector current reaches its maximum, it can reach 4A volts.
