BD681S Overview

As explained above, DC current gain takes into account the rate at which the base current flows through the collector current; therefore, DC current gain for this device is 750 @ 1.5A 3V.As it features a collector emitter saturation voltage of 2.5V, it allows for maximum design flexibility.VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.Maintaining the continuous collector voltage at 4A is essential for high efficiency.An emitter's base voltage can be kept at 5V to gain high efficiency.In definition, current rating refers to the maximum current a fuse can carry for an indefinite period without deteriorating too much, and the current rating of this device is 4A.There is a transition frequency of 10MHz in the part.A maximum collector current of 4A volts can be achieved.
