BD440S Overview

This device has a DC current gain of 40 @ 500mA 1V, which is the ratio between the base current and the collector current.Single BJT transistor has a collector emSingle BJT transistorter saturation voltage of -800mV, which allows maximum flexibilSingle BJT transistory in design.As a result of vce saturation, Ic reaches its maximum value (saturated), and vce saturation(Max) is 800mV @ 200mA, 2A.Emitter base voltages of -5V can achieve high levels 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.Single BJT transistor contains a transSingle BJT transistorion frequency of 3MHz.Maximum collector currents can be below 4A volts.
