FZT749 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 100 @ 1A 2V DC current gain.This system offers maximum design flexibility due to a collector emitter saturation voltage of 600mV.Single BJT transistor means that Ic is at Single BJT transistors maximum value (saturated), so the vce saturation(Max) is equal to 600mV @ 300mA, 3A.Keeping the emitter base voltage at -5V can result in a high level of efficiency.Normally, a fuse's current rating refers to how much current it can carry without deteriorating too much, which in this case is -3A.100MHz is present in the transition frequency.Single BJT transistor can be broken down at a voltage of 25V volts.A maximum collector current of 3A volts can be achieved.
