BD442S Overview

In this device, the DC current gain is 40 @ 500mA 1V, which is the ratio between the base current and the collector current.As it features a collector emitter saturation voltage of -800mV, it allows for maximum design flexibility.Saturation of VC means the Ic value is at its maximum, so vce saturation (Max) is 800mV @ 200mA, 2A.Single BJT transistor is possible to achieve a high level of efficiency by maintaining the emSingle BJT transistorter base voltage at -5V.The current rating of this fuse is -4A, which means that transistor can carry an indefintransistore amount of current wtransistorhout deteriorating too much.The part has a transition frequency of 3MHz.Maximum collector currents can be below 4A volts.
