BD681 Overview

This device has a DC current gain of 750 @ 1.5A 3V, which is the ratio between the collector current and the base current.With a collector emitter saturation voltage of 2.5V, it offers maximum design flexibility.VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.In order to achieve high efficiency, the continuous collector voltage should be kept at 4A.The emitter base voltage can be kept at 5V for 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).TO-225AA is the supplier device package for this product.The device exhibits a collector-emitter breakdown at 100V.Maximum collector currents can be below 4A volts.
