BD440 Overview

This device has a DC current gain of 40 @ 500mA 1V, which is the ratio between the collector current and the base current.Single BJT transistor has a collector emSingle BJT transistorter saturation voltage of 800mV, which allows maximum flexibilSingle BJT transistory in design.Vce saturation?means Ic is at its maximum value(saturated), and the vce saturation(Max) is 800mV @ 300mA, 3A.Keeping the emitter base voltage at 5V allows for 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 -4A.Product comes in the supplier's device package TO-225AA.This device displays a 60V maximum voltage - Collector Emitter Breakdown.Collector current can be as low as 4A volts at its maximum.
