BD438STU 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 30 @ 10mA 5V DC current gain.A collector emitter saturation voltage of -200mV ensures maximum design flexibility.Vce saturation?means Ic is at its maximum value(saturated), and the vce saturation(Max) is 600mV @ 200mA, 2A.The base voltage of the emitter can be kept at -5V to achieve high efficiency.A fuse's current rating indicates how much current it will be able to carry over an indefinite period, and this device has a current rating of (-4A).3MHz is present in the transition frequency.The maximum collector current is 4A volts.
